Microsoft and a bunch of other companies have launched the Web Services Interoperability Organization.

PressPass: How does WS-I plan to deliver on these goals?
Lewin: I think you’ll see WS-I active in three key areas: Web-services interoperability guidance and testing to accelerate customer deployments, Web-services profiles help with adoption and support for key Web-services standards, and a roadmap to help customers understand the long-term architectural directions of Web services.
