I was scanning the webrtc drafts to figure out what is
specified regarding NAT traversal, firewall and proxies.

draft-ietf-rtcweb-use-cases-and-requirements 
<http://tools.ietf.org/wg/rtcweb/draft-ietf-rtcweb-use-cases-and-requirements/> 
mentions
1)  NAT/FW that blocks UDP :

Ok, This is achieved by supporting ICE-TCP

2) FW that only allows http:

How is this supported?

What about enterprises that only support proxies?

In the google group discussion, Justin was mentioning
that browser could connect with a proxy (http connect)
even for TURN traffic and also mentioned supporting
an enterprise TURN server.

Will this make into one of the webrtc rfcs?

thanks,
Binod.
