Inscribed Rectangle

Hello All-

   I spoke with a client recently who wants to use some US County and US 
City polys as the basis of some demographics work. He asked for the 
polys, bounding boxes on the polys, and a maximum rectangle that would 
fit inside the poly. I sid that I had not heard of that before, but I 
would look into it.. after (a small amount) of thought, I told him that 
there were a lot of difficult or ambiguous cases that would come up.. 
So he replied.. ok, just any rectangle that fits in the poly, trying to 
be as big as it can be..

   So I dont know how I might go about this..  Any ideas?

   thanks
     -Brian
