One thing I haven't discussed yet is the new profile/message context 
APIs.  Currently the plans for these aren't in a form anyone other than 
probably Brent or I to consume.  We're working on getting that fixed.  I 
can say that the new APIs will allow any information stuffed in to the 
context to be carried forward from the authentication engine in to the 
attribute resolver (and beyond).

Now, this doesn't magically do what you want.  For such information 
people will still end up having to write a login handler that knows what 
information is important and puts it in to the context.  But there will 
at least be a clean way to carry all of that data threw the entire process.
