Thanks for setting me straight, Johannes!
Now that I know better, what if we consider an email address being mapped to
an OpenId Endpoint URL (instead of an actual Identity URL)? The mapped
endpoint URL could go through existing OpenId discovery mechanisms, and be
used in the current protocol.
All we would need to specify in such an extension would be the
email-address-to-OP-endpoint-URL mapping mechanism (This was proposed a
while back, but not as an extension).
