If RPs do indeed include the "http(s)://" as part of their
account identifiers, then yep, there's a migration problem.

In any case, I suggest that y'all rethink the notion that
URLs that only differ by that "s" can represent different
entities.  I note that the above statement about what
OpenID needs makes an implicit assumption that such URLs
would represent the same entity.
