I will be speaking at our DIDW session first, followed by Mary & Patrick, so I'll have plenty of time to get to the party.
I'll be talking about SAML AuthnContext and OpenID PAPE, and a Concordia type usecase involving both protocols that hilites some discontinuities between the two.
p.s. If the bouncers at the Ping party hassle you at the door, just tell them that you are with me. I assure you that you will be given the appropriate level of respect.
