As others said,
Why not several low cost FPGAs on a board ?
This could reduce the fixed costs (over performances).

The big cluster is a good idea, but of course, it means that someone
have to buy this cluster (alone). It is probably more realistic to
have smaller boards.
By the way, I'm pretty sure we could get some free FPGAs from Xilinx
if we build such kind of platform.

PS: talking about microcontroler, why not an AVR instead of a PIC? :)
