for those of you interested in further SOA education, i recommend checking out Microsoft BizTalk Server: Service Oriented Architecture.

BTW, Attend this webcast Real World SOA: Enabling a New Generation of Dynamic Applications, here's the description:

In this webcast, we discuss the Microsoft vision for service-oriented architecture and show how Microsoft supports this vision by way of an integrated platform. Learn how you can use your existing systems, line-of-business (LOB) applications, and data and expose them as services (using the .NET Framework and adapters). We then show you how to use Windows Workflow Foundation and Microsoft BizTalk Server to compose those services into composite business processes and workflows, which you can then use to create new dynamic applications that consume your service-oriented infrastructure. Join us to discover how you can deliver new capabilities to your business users by taking advantage of these tools and techniques.

Presenters: Burley Kawasaki, Group Product Manager, Microsoft Corporation, Mark Baciak, Architect, Microsoft Corporation, and Thom Robbins, Director, Microsoft Corporation
