A forum for developers and IT Pros to discuss about interoperability has been launched on MSDN forums. The Interoperability forum is getting started with several posts and a FAQ. You can join in by logging in with your Live ID.
The Interoperability forum has three main areas:
The first aims to facilitate general conversation, the next to discuss and resolve technical issues related to interoperability, and the third to talk about how Microsoft should adhere to industry standards.
