Yes, oddly enough, I was recently shown that several people can connect to
one person, and that person can see all connected to them, but the others
can only see the one (both video and chat window). This is IMHO a pretty
cool feature, which would be perfect for a teaching environment, where the
students connect to the teacher's machine. This way the students can't chat
to each other instead of listening to the teacher. Unfortunately this also
has the drawback of not allowing for any sort of panel discussion. This
would require a reflector.

This ability to deny direct connections is on the MAC version already, and
the PC users have been waiting for this feature to be added. I have also
been knocked off of a reflector by having a person connect to me directly.
The only thing you can do to disconnect is to close CU-SeeMe completely. If
you restart CU-SeeMe soon, the person is insistant, they can reconnect to
you repeatedly.

True again. If you have an external modem as I do, you can look at the send
and receive lights after disconnecting, and can tell when the data flow has
actually stopped. After the data stops you should be able to connect to
another site and actually get there. The data seems to get buffered at my
ISP and continues for up to a minute or more at times. If you have an
internal modem, I would suggest that you just take your time before trying
to connect.

On the other hand, the software is still free, and works great when you
don't have to deal with people like that. Keep up the good work, Cornell.
