A Google TechTalks described on You Tube as: Two of the most active areas of development on the Internet are the rise of Internet identity, in several approaches, and the bloom of collaboration tools such as wikis, on-line conferencing, Web 2.0 tools, and social nets. Internet scale identity is advancing rapidly in two directions - federated identity (ala SAML, etc) and user-centric identity (ala OpenId, etc) and offers some interesting opportunities for the integration of these approaches. In the collaboration tool space, the limited confines of individual social networks and the need for management across a suite of tools is driving the need for better integration as well.
