Sure enough, it's not a fake -- while there are lots of audio and video cables coming off of Conan's MacBook Pro, when they show the desktop (Leopard) and later on bring in a third person, you can see that it really is iChat, running as normal -- the cables are likely just to grab the audio and video for the broadcast.
Unfortunately, this also shows off iChat's limits -- while the technology is cool, it won't necessarily make the people you call any more interested in talking. Odds are that "drummerboymax08" isn't that interested in chatting with you either.
