Will take place May 1-3, 2006, at the Computer History Museum in Mountain View, CA. If you are new to the subject of digital identity and want to find out what it is all about, you should attend the first half day: there will be tutorial etc. If you think you get it, and want to corner the people responsible for much of what is going on, come the second and third day.

Subjects will include Yadis, LID, OpenID, i-names, SXIP, InfoCard and Higgins. Both commercial and open-source efforts will be discussed. I expect it to be very hands-on and interactive.

Here is the wiki where you can add topics you'd like to see covered, or what you'd like to contribute.

The official announcement is here on Phil Windley's blog.
