I don't think it does - although I haven't tried it on Triton yet, AIM 5.9 and below only support 1 person video. AND since Triton is based on AOL's Instant Messenger and NOT AOL Instant Messenger (AOL'S IM is the version in the AOL client, which is in my oppinion, much better) and AOL's IM does NOT support it, my guess is that ALL versions of AIM only support 1 person video chat.
BUT the chatrooms can have a ton of people in them.
