I have a system built around a KT400 mb with a 2500xp processor. I have tried a video link using netmeeting and hotmail with a modem link which reports a speed of about 44k bps. The sound is an on board system. The video is a bit jerky but acceptable while the sound is very poor and has an annoying echo. Is this all I can expect from a modem link. Is the result dependant on the software. I only have a cheap USB Zoomcam, would a better camera help. Would a separate sound card help. Would a direct PC-PC link be better, and if so how do you set this up.
