SAP Portal and MS Sharepoint

We are interested in knowing if companies have successfully integrated SAP Portal and MS Sharepoint for content management and collaboration. We've found lots of documents that talk to it, but so far can not substantiate any actual successful integrations between the two products. We plan to deploy EP 6.0 early next year and already have a Sharepoint v2 implementation running. Our desire is to use the Sharepoint product for content management and collaboration purposes. We've found many instances where Sharepoint uses the .NET connector in the NetWeaver architecture for pulling data out of SAP. Any feedback is highly appreciated.
