Subject : CuSeeMe

Hi every body there !

This contains 2 sections :

1 - who i am (or who we are), and what i want to do with CuSeeMe (the story=
=20
you ask for !) :-)
2 - suggestions for future realeases of CuSeeme :
2.1 - what may be exists yet but is not clear in the present release,
2.2 - what would be useful and, according to me, urgent,
2.3 - what would be comfort functions.

1 - I took one month ago a personnal suscribing to the Internet, in a=20
private provider which is
France Pratique, himself provided by Internet-Way (IWAY).

I made this as well as for personnal use, as well as for professionnal=20
evaluation and exploration,
since the Ecole des Beaux-Arts in Paris wil have its own internet access=20
through the Minist=E8re de
la Culture at the end of January.

I am in charge there for all technical evaluation, internal technical=20
consulting, new installations,
and diverse things were i am able to tell something, or when i am asked=
for...

Within this, i am looking at the moment for what could be the sp=E9cific=20
applications of the internet
ressources for the Ecole, further than the only consultations of the web=
pages.
And as you can suppose, i find a lot :-))

One of the most interesting is your software CuSeeMe !
(some of others are : VRML ressources, FTP servers, email, and all those...)

i have downloaded it, read your .txt files and i am very pleased to be a=20
CuSeeMe tester.
So i did it.

My workstation is a pentium 133, 32 Mo RAM, HD 850 Mo, graphic card Matrox=
=20
Millenium 4Mo,
modem 28.8 on the RTC (ordinary phone line), screen 17" running at=20
1024*1280. I also use my
former 486 DX2 in workgroups with windows 3.11 as a complement and for=20
having a look at
other documents when working (eg. it is very convenient to do so when you=20
learn a new software
and want to have the help files at the same time you experiment the=
commands).

I use Trumpet Winsock as TCP/IP stack.

I bought a small connectix camera and during a lot of hours, i made some=20
connections to
reflectors (or i tried to make... !), and i went to IRC channels which are=
=20
speaking about cuseeme,
and made some experimental connectings 1 to 1 with volunteers i met there. I=
=20
must say that
every body is quite willing to forward help :-)

I have also the idea that as the connectix camera is new and not expensive=
=20
at all, a lot of people
just bought it recently and every body is making his trials... so that you=
=20
can find at the moment
on the IRC channels a lot of people who is very ready to do the trials with=
=20
you, including trying
for one hour long (!) to have a correct connection with you. It is very=
fine.

So that i can tell you in section 2 of this file, what i have noticed, and=
=20
what ideas i have for the
further releases of CuSeeMe.

Applications i can see for the Ecole des Beaux-Arts are the following :
- teleconferencing with other schools or university whith who we are in=20
permanent
exchanges (students travel, exchnages of teachers...) in the domain of fine=
=20
arts.
- teleconferencing in the particular application of a course which could be=
=20
heard and
seen in another school,
- teleconferencing, offline from the internet, on the LAN of the school,=20
and on the MAN
of the Ministere de la Culture in Paris,
- teleconferencing, offline of the internet, with other institution, using=
=20
a ISDN link.

2 - comments and suggestions :

2.1 what may be exists yetbut is not clear in the prsent release :

- the use of the filter in the chat window : how to use it, has the button=
=20
to be active to send a
message. Sometimes, it seems that when you send a message, it is not=20
received on the other
side.

- Erase the former called number in the conference/connect window : all the=
=20
number you have
called formerly stays in that scrolling windows. It is useful for somme of=
=20
them, but for some
other, you would like to erase them.

2.2 : what would be useful and, according to me, urgent,

- when you have established a connection, it runs allright for a while, and=
=20
then, either it
disconnects alone, or the video windows of the remote correspondant=20
disappears, although it
seems that the connection is still active (conf=E9rence/connect options has=
=20
the disconnect option
active and connect option inactive, and the remote correspondant sometimes=
=20
goes on seing
you),

- It seems that both correspondant have to disconnect at the end of the=20
communication : if one
disconnects, it seems allright both side, but the one who has disconnected=
=20
can't do anything if
the other don't, although the conference/connect options are showing=20
disconnect inactive and
connect active. So you don't have any other solution than exit cuseeme and=
=20
launch it again.

- when you have made a connection, and you have finished, and you want to=20
try another one, it
seems very difficult. The messages are "connecting to <ip adress>", then=20
"connected to <ip
adress>", and then all at once "<ip adress> is disconnecting from us", and=
=20
that, nearly all the
time. you have to exit cuseeme for a while and come back later. (may be the=
=20
same problem that
the above point?).

- Status bar is often showing "ready" instead of "waiting for a connection".=
=20
Is it the same thing?

- messages in the status bar are not updated by themself. you have to scroll=
=20
down one menu and
close it to have the update of the message in the status bar.

- it would be very useful to be able to use cuseeme on a LAN, offline of the=
=20
internet.

- it would be useful to have cuseeme running in background, permanently, in=
=20
a waiting status,
with a beep sounding when somebody calls you. so that you can do anyother=20
work, but you are
joinable.

- it would be great if the chat window could send you back a mark when your=
=20
message is arrived
to the remote correspondant. So you can know when he has your message, you=
=20
are not
wondering if it is not lost, and you can wait the good time before sending=
=20
another message. At
the moment it is quite blind...

- do you think to find a solution to join somebody at a fixed adress : at=20
the moment, when you
use a private provider, you have a different IP adress at each session you=
=20
do on the net. So that
you have to use the IRC first, or the ordinary phone, to make an=20
appointment, and to give the
other one your IP adress. Phone call is not convenient, using the IRC loads=
=20
the net. In the same
way, for the chat window (cf. the above point) which is too blind, the=20
common way is to keep on
using the IRC channel to send the messages. It loads the net too.
Would it be possible, for example, to use in the future the email adress or=
=20
something like that, to
join somebody at an adress which would be always the same?

2.3 - what would be comfort functions.

- within a connection, send a snapshot, or a file, on the model of sending a=
=20
file in the DCC/send
on the IRC,

- Save or record all or a part of the connection, at least the chat window,

- on the local machine (so that it does'nt load the net), use an algorythm=
=20
which allows to rise the
resolution of the image by a software interpolation, so that you can rise=20
the size of it too, on the
model, for example, of image/imagesize in photoshop.

Last comment :

i find your cuseeme software very, very good although it is not matured at=
=20
the moment. But i
hope it will be soon, and i certainly wil be a user. congratulations
Anyhow, how do you think it will take position in regard of the Intel=20
product (which i don't
remenber the name), allowing a video conferencing, and sharing the software =
=20
used by one on
both side of the connection, using a ISDN connection (it is a good product,=
=20
but more expensive -
a lot more - and requires heavier infrastructure as a personnal access to=20
ISDN, which is more
expensive too).
