Here's one I prepared earlier: the BBC's Tech Refresh project

During 2008, the BBC is undertaking a “Tech Refresh” project, replacing the platform underneath bbc.co.uk with a data-driven, RESTful service oriented, platform independent architecture. This session will describe what we’ve done so far, what we’re aiming to do and how it will allow the BBC to support social networking, opening up our data, OpenID, and more. We will focus specifically on our next-generation Identity (single sign-on) platform, providing the basis for our personalised services and capable of implementing standards such as OpenID, Oauth, SAML etc.
