I hadn't even noticed until today. I was video chatting with my dad and the plus button on the bottom was actually black. I clicked it and it came up with several names, one my g/f. So I added her and it did the cool thing were it moved my dad to the left and added her window to the right. It worked great!! There were a few seconds of real grainy-ness as it adjusted to another video source, but after a few seconds we were looking as usual.
So if you're still having problems with iChat and multi-video as I was, try updating to the latest quicktime and see if it solves the problem.
