Email Address to URL Transformation

[SitG Admin]

>I don't quite understand your proposal.  Can you elaborate?

The part I'm solid on so far is that, since Yahoo owns Flickr, and 
hosting the service at yahooapis.com indicates that it doesn't *need* 
to host the service at the domain it acts for, could it have another 
part of the requested URL specify which domain it was answering for?

The part I'm still thinking over (not sure it would work) is;

http://webfinger.google.com/?site=goohoo.org&id=user
http://webfinger.yahoo.com/?site=goohoo.org&id=user

Where "goohoo.org" is a joint Google-Yahoo community.

Standard complications apply :(
