[OpenID] OP-initiated RP discovery

>That sounds like what we call an "unsolicited assertion".

I thought those were non-direct OP-RP communications, with the user 
carrying the payload? The diagram I found seems to support this:

The use-case would be a Relying Party running on a server only 
available through the Tor network; *but*, that server would 
asymmetrically be able to make requests to other servers on The 
Internet, even though most servers can't access .onion TLD's. I 
*think* OpenID could still work in this way, over Tor, because the OP 
is returning documents as a response and not a separate request of 
its own.
