Map/Normalize Email Address to IdP/OP URL (Was [PROPOSAL] Handle "http://user at example.com" Style Identifiers)

[Jonathan Daugherty]

# I think that all this discussion about email userid is moving us off
# track.  My original proposal was that the email maps/normalizes to a
# URL of an IdP (the userid is ignored/not used).
# 
# So, 'xyzzy at any.edu' would be treated as if the User had entered
# 'http://any.edu' (the URL of their IdP/OP) into the OpenId login
# form.

Then why not just enter 'http://any.edu' or 'any.edu' instead?
