Interesting:
1. Robert Sparks is now working for Tekelec?
2. I am not sure if this is relevant at all for Kamailio. This draft 
does not change the behavior of routing back the responses. Thus, if the 
proxy forks the INVITE and both callees send 200 OK at the same time the 
proxy still has to forward both of them to the caller. This draft is 
more about keeping the INVITE transaction in memory to absorb 
retransmissions. Bogdan, AFAIK transaction are always kept in memory for 
some time to absorb retransmissions. If this is also the case for 
INVITE-200 then Kamailio is in fact not 100% RFC 3261 conform and thus 
does not suffer from the RFC 3261 bug.

One other thing is, that the draft says a statefull proxy must not 
forward stray responses. This is a feature I want for some time now and 
maybe we should implement it anyhow for security reasons.
