This is actually something that is used in the Auth 2.0 spec, where
there can be a Yadis document for an entire domain.

David, although this may be an interesting idea, Yadis (unlike SMTP)
isn't meant for host-global communications. A Yadis document normally
corresponds to a single user record.

Furthermore, a user identifier isn't necessarily a URL. It may very well
be an XRI. So if your iname expires, you could theoretically tie your
email address to your inumber.

In case you didn't read my reply to Martin, there is quite a large niche
of users who don't feel comfortable with OpenID because it requires them
to use a URL for an identifier. An email address is a much more familiar
