I need to say this again: do not be mislead my my email address, as 
I'm only looking at this as a possible skunk-works in parallel to

FWIW, there are several efforts looking at FFT on Cell, with at least
one of them being free as in freedom, ad mostly all done.

This fact has not been lost on certain govt agencies. A back of the
envelope calculation shows that, for about $250K, you can fill the 
garage of a suburban home with PS3's, power them without requiring
an electrical utility upgrade from the city, and break 64-bit DES
keys in about a week or two. All this without arousing suspicion 
by actually renting a space in an industrial park ...
