Actually I think you'd be surprised.  I don't know what Google Talk's latest numbers are, but I bet there is in fact more SIP done than XMPP even across the "Public Pure Pristine Internet".  It's not as much SIP as is done within the same network, but it's a still a lot. 
(of course the real king of "public Internet" VoIP would probably be Skype protocol :)

Right I think we do agree - I was under the impression you were saying we don't need to work with SIP.
