OK. so I don't know much about the gory details of OpenID AX.

Nevertheless, based just on the phrase "Attribute Exchange", it
sure does seem to bear a lot in common with the Liberty Alliance
notion of account linking.

So I wonder how much has already been done, how much would
be reusable, and so forth.  I'm wondering this in the sense of
concepts, design, protocols, code, and whatever else.
