I'm not sure what Nat is specifically referring to, but there was a US
academic institution that provided OpenIDs for "classes" of people... i.e.
students, teachers, etc.

When you signed in for certain application, the OP would respond with the
appropriate identifier for a class of users.

So, imagine I use directed identity in a school application... when I sign
in to the OP, it will return something like schoolname.edu/student as the
identifier.

You could imagine something similar where you could use authentication as a
way to verify that someone comes from some geographic region or has
previously registered for certain entitlements.
