I use iVisit occasionally for my webcam collage portraits. It's a nice little program but buggy as hell. While I've logged many hours with it, I can't really recommend it too highly, at least for stability. Set a time, though, and I will certainly be there and we can have a PANIC like they were originally intended... as a face-manipulation party.
In the meantime, I will stoke the fires of IRC channel #sito on undernet.org servers. Will open that as often as I think of it. Also, we should compile a list of IRC clients for various OS's.
