Just a few info on SIP:

  -> ICE specification is exactly UDP hole punching.

  -> SIP is much more that only audio, video, chat or presence: it's
     independant from media.

> 3. it is extremely light on the server resources.

  -> With SIP, server should only be slaves from clients: this is
     the whole new theory about it. In the specification, server has
     only one role: routing/finding users.

  -> "p2p-sip" working group has just been created 2 weeks ago.
