I think IPv6 (IPsec?) has nothing to do with NAT traversal solutions, 
except to replace them.  IPv6 seems to have lost the battle (not the 
war).   Do you really want to push for IPv6, seeing how it has lost the 
battle?  I can add it as a feature if you like, but wouldn't replace the 
original.  I'll change the wording to
7. Traversal techniques such as TURN, STUN, and ICE to make SIP/SIMPLE 
behave with NAT, firewalls, and SBCs.
