I can't comment on that. :)

It's long, but the basic idea is not all that complex.

What's in libjingle is not (yet) ICE, though it's ICE-ish. I would think 
that eventually it will be brought into line with the ICE spec itself, 
though we always may do things a bit differently in Jabber land because 
XEP-0176 specifies that we send one "candidate" at a time (in part 
because we have a good XMPP connection between the two parties) whereas 
in SIP land they send the full candidate list at once.
