I am the Coordinator of Multimedia Technology at Multnomah Education Service
District. My job is to support teachers and learning organizations in the
county. CU-SeeMe is becoming widely know as a wonderful tool for teachers
and students. All of a sudden.........CU- SeeMe has been banned by MIS and
one of our local InterNet providers. Below is some of the arguments about
the use of CU-SeeMe. Please respond to the issues below so that I am able to
work toward having students use your fine tool.

Additionally I have also added a letter from a teacher to help you understand
the importance of the CU-SeeMe tool.

Dear Dan,

Teleport, my provider for more than two years, suddenly cut off access to
using CU-SeeMe to all its customers, without any notification. Which means
all the work I have been doing with Texas and South Africa, is being held
up, until I find another provider. I talked with Lynn Anderson and she may
be calling you about my situation. I am not familiar with either the
Portland School Network or the ESD network but I know what I need to
continue. I need a dial up IP or PPP account, which can run Netscape,
Eudora, and CU-SeeMe-current version. I don't know if you can help me but I
would appreciate anything you could do .
I am enclosing my speech that I delivered to the board in its final
form,as I know you were interested in its content. Lynn seemed to think
the board and Dr. Bierwirth were impressed. I would appreciate feedback
from you as well.
As of now, I can't invite you for a demo of CU-SeeMe. You'll have
to wait until I get a provider willing to let me use it. I can say I will
keep my teleport account until I get another one, but I will be looking for
one ASAP. I will keep you informed of my new address when I receive it.

>Dr. Bierwirth, and board members,
> Thank you for this opportunity to address you about the uses of
>Internet in the elementary classroom.
> I have been using the Internet as an educational resource for about
>a year in my fifth grade classroom, using my own Internet account, one
>computer, and one phone line.
> During the past year my students have been involved in many
>projects using electronic mail. We have established an on-going
>correspondence with a school in Pietermaritzburg, South Africa, where the
>students are electronic mail penpals, known as keypals. Through this
>project, our students have exchanged information about the others
>geography, culture, customs, language, history, measurement systems,
>wildlife, and political structure. "To discover that many different ways
>of doing something can all be right" was an observation of one South
>African student. Other benefits from this one activity include using this
>new technology as an effective way of gathering information and the subtle
>art of communicating effectively.
> This school year, we are again communicating with South Africa,
>extending this established collaboration, working on a project to provide
>needy students in South Africa with discarded books.
> Last year, we also helped the students of Kobe, Japan, recover from
>their devastating earthquake, collecting school supplies. We corresponded
>with coordinators of this project using e-mail.
> Another exciting form of communicating via the Internet is through
>the use of free software from Cornell University called CU-SeeMe. This
>software allows my students to video-conference with other classrooms,
>scientists, and history experts over the Internet , with the use of a
>small, black and white camera. Students can meet and converse with people
>in France, England, Australia, Norway and Texas, for example, all at the
>same time. A direct, one-on-one conference is also possible. I have been
>collaborating with a third grade teacher in San Antonio, Texas, and we are
>currently planning units involving CU-SeeMe in the area of life science
>and U.S. history.
> It is truly exciting to watch and participate in one of these
> My students have the opportunity to participate in demonstrations
>of science, view the shuttle astronauts in orbit, share information with
>other classrooms around the world-in real time, participate in live
>competitions, and interview experts in their given field, specifically
>addressing educational outcomes in the areas of communication,
>self-directed learning, collaboration, and production. Dr. Bierwirth, Dr.
>McElroy, the board, and audience members have an open invitation to visit
>my classroom at Rose City Park for a demonstration of these wonderful
>learning tools.
> One of the draw backs to all this is the situation that face most
>schools in our district today: only one line, and/or one connection.
>Scheduling the use of this one computer is a challenge. Additional
>computers and the installation of computer networks connected to the
>Internet would provide the opportunity of what I am doing to every student
>and teacher in this district.
> My students come in every morning with a great enthusiasm for
>learning, knowing that they may meet someone in Tokyo or Texas without
>leaving their classroom, and enjoy sharing their experience with
>classmates and parents, which they demonstrate in many different ways.
>Through the instantaneous response the Internet offers, my students have
>reached out and joined a global consciousness, which has had an enormous
>impact on their perspective of the world.

Let me know what you think.

>> each router can be attempting to route the traffic for 32 modems, the
>> degradation affects the other users on that router.
>> Teleport has always maintained that the overburdening of
>> resources by one user is unacceptable, when that behaviour affects other
>> users on the system. Our decision to move from discouraging CU-CMe to
>> blocking it is an extension of the rule regarding system resources.
>> A quote from the 'rules' help file states the following:
>> Here are the things you MAY NOT DO with a Teleport account:
>> 5. Consume excessive system resources, such as disk space, RAM, or
>> processor time.
>> For example: do not fill up public temporary space with files,
>> run programs that eat up huge amounts of RAM or CPU. You also
>> can't run processes while you are not logged in (leaving
>> screen processes running, or running an IRC bot, for example).
>> We hope that the creators of CU-SeeMe will design a future release to
>> handle modem communication better. Until such time, CU-SeeMe will not be
>> usable through our service. Questions regarding this decision can be
>> directed to
