You are aware of the SMB2 issue with VFP, Access and other ISAM file-based databases? It will likely never be fixed. See the thread http://www.levelextreme.com/DataEntryThreadView.aspx?ID=1430067

Also, Michel Fournier, the owner/operator of the UT, found that the latest available VFP OLEDB provider is not reliable under load. After much back-and-forth with MS, that's another issue that will not be fixed. Arguably, this shouldn't be too much of a problem because OLEDB is being deprecated by MS. But, the situation with ODBC is even worse, the latest driver only supports VFP6, and none of the data/database changes made since then are supported.

Interop with 64-bit apps is challenging. Might not be a big problem now but it'll only get worse.

MS is not so much actively trying to kill file-based databases, instead it's neglect and/or lack of testing. SMB3 is coming out in Windows 8/Server 2012, both are still in RC. I don't know if anyone has set up an environment with these OSs for testing but chances are the community is going to have to do it, because MS probably won't.
