> Comments are always welcome

The short mention of the ICE Agent in draft-ietf-rtcweb-overview-01 may need
some more explanation if SIP oriented ICE is implied and if not, the flavors
of ICE for other protocols, such as Jingle which has different signaling, as
mentioned in the I-D, or/and need other extensions, such as for RTSP
(draft-ietf-mmusic-rtsp-nat).

The draft-rosenberg-mmusic-ice-nosip from 2009 explains these issues,
including the fact that not all protocols can use ICE.

Since SIP may or may not be the signaling protocol, the implied meaning (or
is it?) should be explained along with the issues and options.

One option that comes to mind is using HIP with its own ICE solution
(RFC5207) but having the advantage of working with _all_ application
protocols, besides transition to IPv6, mobility and VPN-like security.
For maximum flexibility and applicability IMO in environments using HIP.

Some more text is desirable discussing the above.

I have taken the liberty to copy the authors of RFC 5207.

Thanks, Henry
