We've been working on integrating Crystal Reports RDC (8.5) with
VFP. It works well - we've got a VFP form that can either view
the report (like VFP Print Preview) or serve as the print engine to
send the report to print/email/fax.

It's not completely finished, but we've gone through the excercise
of figuring out which Crystal Reports methods/properties are needed.
