I was hoping someone made a bitstream for something else other than SHA-256 and scrypt mining for a BitForce or X6500.
I haven't spent any time trying to reverse engineer it, but for most applications it's not very useful since very few of the IO pins are available. Further, the JTAG has been disabled although that's only a quick fix.
TL;DR: (IMO) The hardware configuration is limiting. It'd make more sense to have the FPGA's reballed and put onto a proper dev board.
