"This approach seems to be one that could be useful in many BI type projects, and to a large extent, seems to be a good use of Powerpivot as a way to prototype projects"

Thank you Steve.

I can write many hundreds of sheets of paper how BI projects are developed.

The word prototype seems not to be invented.

I have been using PowerPivot for a while. Microsoft has don'e a good job but I miss some basics like an API compared to the main competitor QlikView. PowerPivot is however easy to implement, costfree and a part of Excel.
