Yes, SIP can get very hairy, because it's primarily xml -ished based. The proper way to make MSN Messenger work is using Universal Plug n Play to do nat traversal. http://linux-igd.sourceforge.net will make this work (every feature except file transfer, which we at the UPnP forum are trying to get Microsoft to hurry up and fix (along with many router vendors)).
If there was indeed an SIP conntrack however, it would be so much nicer, because there are a lot of packages coming out that use SIP but do not use UPnP. It's just a matter of sparking enough interest in it to get someone knowledgeable in netfilter to write one (or someone learning from scratch).
