I thought it had come up.  I recall it even being on the website at one
point, but I can't find it now.  But for the record, I agree.

The only proper way to do email to URL mapping is via some new DNS record
type, which would totally delay adoption, to the point it's not even worth
talking about.

I've heard talk of polluting the top-level directory even more like
robots.txt, favicon.ico, and cross-site-security.xml (or whatever that
Flash file is)

If a user entered:

   Username: [ brad   ]  From (OpenID server): [ ]

Then a consumer could hit

And get back:


But I hate the whole idea.

Already I'm finding that all the demo sites using OpenID are starting to
use the recommneded form field name and my browser is auto-completing my
identity URL everywhere... so I'm happy.
