The MIT Kerberos Consortium held a conference in October and is now making slides from presentations available here online. These include slides from Microsoft Chief Architect for Identity Kim Cameron's keynote address and from a panel including NASA and Cornell reps.
Meanwhile, the feature set for Version 1.8 of the Kerberos authorization and authentication system is set and delivery is slated for March.
The group does have a blog, but it isn't updated frequently. There is a full batch of documentation here, though, to keep you busy.
