[OpenID] Relationship of OpenID URLs and e-mail addresses

[Hamish Allan]

On a not entirely unrelated note, has anyone considered the use of
OpenIDs as email addresses?

Imagine a service openidmail.com which offers email addresses based on
OpenIDs. I can immediately set up my mail client to connect to
smtp.openidmail.com and send email with a from: address of
openid.aol.com/me at openidmail.com and a to: address of
you.myopenid.com at openidmail.com. You can receive it by setting up your
mail client to receive mail from imap.openidmail.com. Authentication
can be handled using e.g., session cookies as passwords for TLS.
Spammers would presumably set up their own identity providers, which
could quickly be blacklisted.

Has this already been discussed?
