The new draft with the SAML mapping seems to me to be harder to follow 
than the last, but having said that you seem to have done a great job of 
keeping the SAML complexity to a minimum.

I was a little disappointed to see it explicit that non browser clients 
are not being considered, feedreaders and blog clients seem extremely 
important to me and I worry about leaving them out.  It will be 
interesting to see if they are accomodated in WARP and whether Sam is 
going to propose some sort of federated digest authentication scheme, 
potentially similar to the one proposed by Philip 
http://www1.ietf.org/mail-archive/web/dix/current/msg00368.html. 

A scheme such as this would benefit from sharing a common definition of 
persona-url and persona-document with DIX. Has there been any discussion 
on moving the persona-url and persona-document definitions out of the 
DIX protocol specification and into its own specification. They seem 
more broadly useful and the corresponding specification can build on the 
Yadis work. Are any of the Yadis folks thinking of submitting a draft to 
the IETF?
