that's right @progrium, RelMeAuth (nice suggestion) works for any #OAuth + rel-me site, and enables auto-fallback with use of alternate identities for authentication: 1 user enters their site URL; 2 iterate through their outbound rel-me links; 3 if a rel-me destination is up, and rel-me links back to user's site, and has OAuth endpoint, then do OAuth authentication. Thus user links to their RelMeAuth profiles in preference order, and authentication code tries them in order. e.g. Twitter, Identi.ca, ... etc. No more OpenID server/delegate single point of failure, nor need to learn yet another XML format.
