The problem is the audio bandwidth. Until someone comes up with a better audio compressor, you need at least 16kb to get minimal audio, and you just can't hose that through a 14.4 dialup. 0.83b3 is just out and has MUCH improved audio handling (but it'll freeze the video when someone's talking, even over a fast direct hookup). We need about a factor of 4 improvement in general bandwidth to really make this tecnology work. Then, of course, everyone'll want color. 8-} Chris --------------------------------------------------------------------- Christopher S.
