Phil Windley, Kaliya Hamlin and Doc Searls produce the Internet Identity Workshop twice a year. One way to track the vector of developments in user-centric identity is to record the milestones of the workshop each year.
The 6th Internet Identity Workshop is May 12-14 in Mountain View, CA.
We have booked the 7th Internet Identity Workshop for November 10-12, 2008 at the Computer History Museum in Mountain View.
Following are links from earlier Internet Identity Workshops (These include Phil Windley's characterization of the developments, some of which were based on some earlier comments from Johannes Ernst):
#1 Oct 2005: initial meeting and introductions to projects being worked on.
#2 May 2006: proponents of multiple identity protocols start dialog about how they can work together.
#3 Dec 2006: small-scale interoperability and some consolidation.
#4 May 2007: interoperability demonstrations of Information Cards and lightweight solutions converge on OpenID.
At the 5th IIW in Dec 2007 OpenID, CardSpace, and SAML, along with supporting technologies, projects, and consortia were accepted. The questions have become what to do now that these foundational technologies have been worked out.

Based on feedback from Newbies 4 Newbies the language describing usercentric identity and the topics covered in the even have been improved. Their feedback is also helping shape the content of our introductory day. http://iiw.idcommons.net/index.php/Iiw2008a
