And in between. We (InSoft) do a videoconferencing system called
Communique! (yes, the ! is part of the name), supporting many-to-many
conferences, with video, audio, a shared whiteboard, and other tools.

Quite true. Communique! has a voice delay--no way around it, short of
paying gobs & gobs of money for a superfast machine & net--but people
adjust to it remarkably well. Of course, *we* notice it, but we run a
lot of our tests between machines that are in the same room, so we
hear both the original speech & the split-second-delayed version.
Not a problem in actual use. :-)

Yes. Unfortunately for those of us who have to sell multiplatform
software, not all vendors have multicasting in their systems yet. :-(
