I would not access a VFP table over the WAN, I would send a request through the 'service program' the request would then get processed at the other end and a small (hopefully) result would be sent back. This would hide the speed of the WAN from the users (they would be using local data). The service program would run in the background or on another PC and keep both copies of the data (local and WAN) in sync. The actual messages sent between the 'service programs' would have to use a small VFP table or ASCII files.

Reachout works great over a WAN. Simple to setup. This service/messaging is basically what people call client server. I can explain that concept to the best of my feable understanding if you like. Can you define your application a little better?
