SIP works well with video; there are many SIP videophones such as the Motorola Ojo. Skype uses On2's VP6 video codec; this is better than older videophones/webcam H.263+, but not as good as Ojo's and Apple iChatAV's H.264. (Ojo is 30fps with no delay, and you don't need to be at your computer to use it.)
I wonder if Skype is still proxying all that video data through relays on publicly-accessible machines. If video gets used much, this could really hurt overall Skype network performance and add strain/overhead/etc to the users who are on open connections.
