I see. I also somewhat like that idea (logic in one place rather than scattered to BO/DB) and working on Rockford Lhotka's distributed architecture (csla.net). But still in that model storage doesn't call BO. It's a long topic (around 60 pages as I remember) just the layers architecture and what/where/why.
If it really is needed as I said before SQLserver has capability to use dlls (and actually SQL2000 already used many external dlls for extended procedures, it just got easier with SQL2005, CLR is built-in). However you're asking this question from VFP perspective and with pure VFP, I don't know.
