OAuth has been insanely successful the past few years in terms of almost
eliminating new password-based APIs.  That said, developers both large and
small have found it to be complex and not as simple to implement as
possible.  We now have the opportunity to develop OAuth 2.0 based on what
we've learned and new methodologies in APIs that weren't prevalent two years
ago.  Overall, I want to modernize OAuth so that it's not just "FooCo
supports OAuth" but rather "FooCo has a million developers using OAuth".

I think that WRAP has a lot of the right ideas (multiple ways to get tokens
and relies on SSL), but ultimately wasn't created in an open process and was
shaped by small number of implementors.  I also think that there are lessons
to be learned from OAuth 1.0 which haven't made their way into the current
WRAP draft.

If I were to write a draft, I'd start with an empty document and merge in
appropriate sections from draft-hammer-oauth, draft-hammer-http-token-auth,
and WRAP.  I'd then probably rewrite half of the text as it gets merged
together.

Eran had a good answer here.

I think it's hard to compare text from this split approach to the WRAP draft
spec.

Yes.  We can split it apart later, but should optimize for a single easy to
understand document.

Yes.  See http://www.ietf.org/mail-archive/web/oauth/current/msg01049.html.
