Re: [rtcweb] RETURN-05

I agree with all of you that this draft is very important to move forward
with.

As stated under Figure 2 in the draft:
   ...This TURN server might be used by an enterprise, ISP,
   or home network to enable WebRTC media flows that would otherwise be
   blocked by the firewall, or to improve quality of service on flows
   that pass through this TURN server.  

I see this (in combination with auto discovery of the "Border TURN server")
as necessary
to finally get a proper solution to the NAT/firewall traversal problem that
has plagued 
real-time communication since its occurrence in the IP world.

I hope for quick test implementations in the WebRTC browsers.

I agree.  I'll note that RETURN covers the auto-configuration portion of
3.3.5, but browsers (and other WebRTC-compatible devices by implication)
should handle manual configurations as well.  (Just a note, it doesn't
affect the spec or RETURN I believe.)

    It must be possible to configure the browsers used in the enterprise
with
    network specific STUN and TURN servers.  This should be possible to
    achieve by auto-configuration methods.
