.Net Interoperability with ALL Products?

Hello all,

Is there a presentation or PDF out there somewhere that documents SAP's planned interoperability with .NET across all of its NetWeaver products?

For example, XI. I was told that you can develop either in ABAP or Java with XI, but what about .Net integration? I'm looking for some answers or XI and the rest of the NetWeaver family of products to see SAP's intentions/plans for them.

Many thanks,

Mike
