Tim,

As a matter of fact, that is exactly how I implemented the bizobj in Steve Sawyer and my book, "Effective Techinques for Application Development with Visual FoxPro 6.0". There is a chapter in the book about N-Tier design, and the bizobj that serves as an example in that chapter has PutFldData and GetFldData methods. Of course this means that the interface objects are a bit more complex because you can't simply use the controlsource (which you can with properties of teh bizobj).
