It uses a standard Internet protocol (SIP+SRTP) as they said in the keynote.
Skype actually does use a proprietary codec (On2 VP7, which Google hasn't released) in their Skype<>Skype video chat. Does Fring use that, or does it support 3G too?
In any case I'd see not using 3G as a major advantage for FaceTime, since H.264+AAC is much better than low-bitrate H.263 used in 3G.

While it draws from a lot of existing standards, it embraces and extends. It isn't interoperable with anything currently deployed.
Which is interesting because one alternative world would have seen them introducing the standard a year ago, to be met by broad acceptance and compatibility at release. They chose not to do this, meaning that early adopters enter a very scarce world.
That would have given away their game with respect to the new iPhone. Also, until iOS 4 is released we can't really say how it's implemented/what it will interoperate with.
