Why not just use XRDS?

If the e-mail address is "rabbit at example.com" the XRDS for http://example.com/ 
  would be requested. Would be trivial to create a namespace for an e- 
mail to uri service that receives an e-mail and responds with a uri or  
failure. This would also allow example.com to implement their own  
logic for unforeseeable transformations such as:

if ($email == 'vp at example.com') { $uri = 'http://bob.example.com/'; }

The downside to this is the route to your OpenID URI is potentially  
controlled by someone else but I think everyone knows that aspect is  
true of all e-mails anyway.
