Section 5., paragraph 1:
>    This section summarizes the requirements; if there is a difference in
>    this summary and the text in the main body of the document, the main
>    body takes precedence.

  Either make sure that there are no differences, or remove this section
  (the document isn't long enough to need a summary.)

  Nit caught by Gonzalo Camarillo during Gen-ART Review:

  The word 'section' is typically capitalized in sentences 
  like '... in Section 3.2 of [RFC4605]'.

This document uses acronyms, such as SDP, without expansion or reference.  Please fix.

Nit:

   to IP multicast group addresses.  This profile of functionality is
   the expected best practice for residential access routers small

Missing "," between "access routers" and "small".

REQ-6 states:

            A NAT MUST NOT forward administratively scoped IP multicast
            traffic (239.0.0.0/8) [RFC2365] from its 'inside'
            interface(s) to its 'outside' interface, unless the NAT has
            been configured to do so.

The semantics of "MUST NOT ... unless configured to do so" are tricky.
As far as I can tell, this requirement is only imposed on the default
configuration.  If that is correct, it might be clearer to state the requirement
in terms of the default configuration:

            The NAT's default configuration MUST NOT forward
            administratively scoped IP multicast
            traffic (239.0.0.0/8) [RFC2365] from its 'inside'
            interface(s) to its 'outside' interface.

I have chatted w/ the authors and they have given me sample text that would clear my discuss. I just need to see a draft.
