RE: [Sipping-emergency] Re: [Sipping-emergency] draft-schulzrinne -sipping-emergency-req-00

>From what I took away from our phone call, one concern was that the
last-mile work needs to block until the geopriv work has become more fully
specified. The short-term issues seemed like they might warrant a separate
document precisely because that document is achievable (and passable by the
IESG) in the short term. 

I also note that the document really doesn't seem to talk about the
trunking-replacement architecture we discussed on the telephone call at all,
except as a component of the end-to-end solution. If that this realistically
the only architecture that will be deployed in the next few years, perhaps
the document should give it more attention.

One nit: if (following I-6) integrity properties of responses from an IECC
are REQUIRED, this entails that authentication of the IECC to the caller is
also REQUIRED (which would seem to contradict I-3). You cannot provide
integrity properties without authentication.
