[OpenID] OpenID - Service Discovery?

[Bob Wyman]

It sounds like at least some of what you're looking to do could be
accomplished using WebFinger. See:
http://code.google.com/p/webfinger/

WebFinger would allow you to take an identifier for a user and retrieve an
XRD that describes the various services publicly associated with that user.
