>This guy sounds like he wants to be empowered. I certainly see how he could feel trapped because he doesn't know how the program works. I've got/had clients that I've taught how to write VFP as well as other software. They are still around. Mainly, they wind up using VFP to create simple stuff. It also addds a few more VFP sales. I don't see this as threatening.

It also means they appreciate your services because they see it's not as easy as they thought.
