>Is it OK to use a VFP database as a backend to a VB application? I know you CAN do it, but I was looking if anyone had any thoughts.

I suggest playing around with accessing your VFP data with ADO (or ODBC if you choose that as your data access mechanism) and see if you can live within the limits of the VFP ODBC driver. One issue that comes to mind is VFP's version of transaction processing. Just make sure you can get the results you expect.
