Assuming you have an open FPGA toolchain (which AFAIK exists for like a year or so), open FPGA designs supported by that toolchain (AFAIK doesn't exist yet). Even if you don't insist of the FPGAs design being open (which is a rather arbitrary border then), you'll have a hard time getting something with performance people actually want to use in the supported chips. It's a nice dream, but not practical right now.
