the internet engineering task force (ietf) presented an audio "multicast"
of their last meeting held in Boston.  A camera was trained on the
presenter, and the video went out over the Internet (highly compressed,
3-4 frames/sec).  participants in the audio portion could hear the
speaker, and those who had microphones could pipe up and speak themselves.

aside from the distinct problem that getting enough bandwidth to
support such an effort is substantial, and that the software to do
it is only in very early research stages, i would expect that audio
and video course telecasting would be a natural internet application.

the video doesn't work too well when people jump around - it tends to
result in multiple images on screen - which may or may not be entirely
suitable to the task at hand.  fun tho.
