I have been doing video chat with H261 (the codec included with old vic)
about 10 years ago and it was quite fluid.
I hope with H264 this should be possible with a decent screen size and
frame rate over today's classic DSL.
So you don't need huge bandwidths for sending mainly a static picture of
an office with ~3 people moving around.
Ekiga supports H.264 and up to SD quality (which I think is enough for
the beginning and costs less to implement).
