I'm aware that this is a FPGA which is doable with Scrypt, however I'd like to go off in a minor tangent. People seem to underestimate how difficult it will be to create a Scrypt ASIC. SHA256 Asics have been used for many many years. They were not new technology, meaning the billions of dollars of research that others had done getting SHA256 ASICs working is not there already for proposed Scrypt ASICs. All the BTC mining ASIC companies needed to do, was make a product that would work for BTC specific hashing, rather than what they were and still are used for, encrypting and decrypting files. The company that decides to start making LTC Asics will need a whole lot more than a few hundred thousand BTC to get their products out the door.

Back on topic, LTC FPGAs actually aren't that difficult to make in theory. LTC's Scrypt hashing requires actually a much lower amount of memory than other scrypt implementations (I believe its 196mb/cycle although I may be off) at that point, or whatever it actually is, I remember the math behind it, but not the actual numbers, you can provide additional hashing power at 1/2 the memory required, and you can still end up with a higher hashrate over current GPUs, while still using fairly inexpensive FPGA technology. So rather than needing to create a new FPGA board that can handle uneconomical amounts of memory, you can just work on designing a chip that will hash fast, and lose performance based on how much memory you can actually supply.

I'll look back over my research tomorrow, and get all of the numbers and such down. I'm tired so I may have said something dumb, I'll correct it later.
