Great! Dial-in details are here:

Agreed as well. We want a very loose coupling. We don't want to
re-invent Persona, we'd like to leverage it. How exactly we'd do that is
still unknown.

Yes, I think figuring out conventions of how an IdP can provide extra
information to a RP would be a good start. Perhaps figuring out a way
where the RP can ask for extra information would be nice.

One option is for the RP to provide a template that is filled out by the
IdP, for example:

   "email": "",
   "identity": "",
   "address": ""

The message above would be sent by the RP to the IdP to request the
information during the login process. The IdP would ask the customer if
it's okay to fill the information out and then provide an assertion back
to the RP that includes the requested information.

Great! Looking forward to it.
