Identity 2.0 / Shibboleth

On philwilson.org I found a post about Identity 2.0 with a link to a really good presentation. The reason that it was interesting to me was that in my world everyone it talking about Shibboleth and extending it to handle multiple federations and allowing it to give out more information about people, which isn't what it was orginally designed for. The Identity people are more about just being able to prove some facts about yourself (one of which could be the university you are studying at and the course you are one). The only thing that Shibboleth seems to give you is the ability to say I am from Oxford and work in the Computer Center without saying that I am Matthew Buckett, so I can remain semi anonymous.
