Perhaps we could start by getting one of the existing compute farms  
with a lot of spare bandwidth interested.

They already exist and turn out a lot of product.  How much product  
are we talking about?  How far out of normal custom chip design and  
fabrication parameters?

Most of us don't have that long.
