If you are supporting XRDS on factoryjoe.com, could we not use this for 
delegation in an EAUT like fashion? The relying party does XRDS 
discovery on factoryjoe.com and gets back your preferred OpenID 
Provider? In the current OpenID 2.0 support, you can specify the 
op-local identifier in the XRDS <Service> section for the OP.
