SIP basically just gets two parties connected. Whether they then 
exchange audio, video or whatever is largely irrelevant. The only medium 
dependant thing I can think of in SIP is codec negotiation. Video 
doesn't bloat SIP at all.

Actually H.323 isn't that bloated - it just uses ASN.1 which most people 
think is a PITA :-(
