I am sort of curious on the criteria  NASA uses to determine
if an upgrade is worth doing. I naively assume this is "merely"
an exercise in the cost of research/development/test vs. the
long run cost savings. 

So they would need estimates for things like the useful life
of a shuttle (ohoh, that's a touchy one {:->), depreciation,
test costs, research costs, price of pork barrels, etc.
