I'll wait for SIP (Score 1)

I've setup an Asterisk server and gotten pretty good audio quality over SIP. A bonus is there are already a variety of SIP soft phones, some open, others not, available for most platforms. I don't know if SIP currently supports video, but I wouldn't expect it to be too long before it does. I'll wait for video over SIP to take off. Heck, I don't even have a webcam....
