Service-Oriented Architecture Presenation

I have to deliver a presentation on “Service-Oriented Architecture” on Thursday. There are a variety of PPTs on the subject floating around MS, but most are internal. My coworker pointed me to one available externally from the EMEA Architects Tour which was delivered by Clemens. There are a variety of other interesting looking sessions on that site, including an AOP w/ .NET attributes session, also by Clemens. Highly recommended.
