I gave my tutorial this morning. The room was almost full, which pleased me. I didn't have enough time--never enough time--to get to everything that was interesting, but I think we hit the high points. I promised people I'd my my slides (PDF) available here.
At the end of the talk, I demoed using a signon.com issued OpenID to log into Jyte and authenticated at signon.com with a self-issued InfoCard using the DigitalMe card selector on OS X. We didn't have time to trace through what was happening, but interested people can at least try it themselves and see what's going on.
