all users have addresses like user at example.com. the same user has an 
alias like 5551234 at example.com (for UAs that cannot handle 
alphanumerical addresses).

some UAs will send a REGISTER with a To: of user at example.com, some with 
a To: of 5551234 at example.com. both REGISTERs needs update the location 
records of user at example.com. rewriting 5551234 at example.com to 
user at example.com for INVITE et al can be handled using enum and/or 
normal alias lookup.

the authentication user could always be required to be 
user at example.com, but I guess that should be handled separately.

I have a feeling this should be handled like a normal alias on REGISTER 
processing + allowed 3rd party register.
