>I don't think it's a really bad idea but wouldn't this be too restrictive? I think one of the advantages of n-tier is the separation of each layer to function w/o too much regards to changes in the other layers. If you don't separate the middle-tier in to separate EXEs or DLLs, you would "corner yourself" in to VFP-only solution. Just my simply opinion.

This is true....you would be creating a bit of a stovepipe but I was thinking in line of the latency issue and minimizing messaging and instancing time between different tiers, which seems to be an issue according to that case study at MSDN.
