There's a (currently slim) possibility that I could secure some time on a few decent sized FPGA systems (although the owners are understandably wary about who they allow to play with their rather expensive equipment), but right now I'm not sure how worthwhile it would be to pursue; what kind of performance would be expected from a Convey HC-1ex (four Virtex 6 LX760s) or possibly an Xtreme Data XD-PCIE3000 with three Stratix IVs per card?

Any ballpark figures would be greatly appreciated, and there's a strong possibility that I'd need someone who knows their stuff to assist me in exchange for a share of the profits if it turns out to be plausible!
