Yeah, I don't think Peter meant to say the same channel... :P The idea is just using the same negotiation namespaces and XEP to describe all RTP media content, be it audio or video. We'd lose in so many ways by doing anything other than staying compatible with SDP here. It's just not a correct use of RTP to pretend that switching payload type is switching media type too.
