I can't remember which people thought this did not solve their problem
but I remember the characteristics of the discussion were similar of
being unclear where this would or would not work and unclear on what
the problem was this did not solve.

So, having re-read all these drafts...
Cullen/Jon,
Why is something like draft-wing-sip-identity-media (let's focus just
on the DTLS-SRTP version for now) not a proper solution to the
problem we
are trying to solve?
The problem being (I think):
Identity Assertion of both the Signalling and the Media, BUT allowing
for relays?
This has the advantage of being end-to-end. I guess the alternative is
to not have end-to-end media identity assertion, and instead have
Alice-to-
her-service-provider's relay, and Bob-to-his-service-provider's-relay
instead.

For everybody's reference, can you point to Dan's draft?
It is
http://tools.ietf.org/html/draft-wing-sip-identity-media-02
other proposals in the same sphere,
http://tools.ietf.org/html/draft-fischer-sip-e2e-sec-media-00

From an end user perspective, I would assert that the

talking, it will be Bob who hears me, and Bob that I hear.
Consider this litmus test:
If the signaling actually came from Mary (perhaps as a
third party),
but the media goes/comes to/from Bob, who should appear
on the caller
ID? I say - Bob.
There is a timing aspect in favor of placing identity in
signaling --
I would like to know whose call is ringing before I answer
(if I do).
You can still have that. Just don't ring the phone until
early media has
been exchanged and verified. Indeed if you were doing an
ICE-style thing
per Dan's draft, you'd get that for free.
