Actually this is where FPGA's have an advantage. They're not useful for the average user, but for hobbyists and anyone with a lot of data can reprogram it for anything. That's why FPGA's are so versatile and exceed ASIC's. You can reprogram an FPGA to work for SHA256 or even scrypt or for doing dictionary generation.
i don't think you can use it for scrypt, at least not this boards without any memory, but i guess many people would like to see a scrypt firmeware
