TCP/IP over a 14.4 kcps+compression modem gets you passable video (try it
with NASA Select) but audio takes over 32 kcps (I believe) and so audio
won't cut it (try it with NASA Select).

Whatever method of bringing people together you use, you'll need *some*
sort of transmission protocol. If you don't want TCP/IP, what do you
propose to get the video and audio bits from your machine to mine?
