now I'm looking at open source alternatives just as critically before deciding what to do next
John, I'd be very interested in what you come up with as alternatives to VFP (forced out) and NET (forced in). I have not seen any discussion of this but is the MS position to move from VFP to NET and if that is not what you want to do to move down to Access?

If it had to be done in April 2007 I guess I'd use Typed DataSets, but promised changes for Linq for SQL would make that preferable if people can wait.
