I've seen it done with OpenID 1.1, though unsure from a technical
perspective exactly how it was implemented. Also unfortunately can't
say who showed it to me, so we'll have to wait I guess to learn more
about it. :-\

Subject: [OpenID] OP initiated and RP to RP flows
There seems to be some talk about OP initiated and RP to RP flows, but I
am not sure if/how OpenID can do it. Can someone more enlightened than
me comment on this please?
For "OP initiated" my searches only found
http://connectid.blogspot.com/2007/05/openid-op-first.html and reading
the OpenID 2.0 spec there is 10.1. "... Relying Parties SHOULD accept
and verify assertions about Identifiers for which they have not
requested authentication" and 13. "Discovering OpenID Relying Parties"
which look promising...
I couldn't find any mention of RP to RP flow (or RP1->OP->RP2). Is this
possible with OpenID 2.0? There are plenty of interesting uses for this
especially with "user not present" scenarios.
I guess both of these are well out of scope. Can anyone confirm?
Thanks,
Andrew
