We will look at FPGA optimisations and software aspects but I won't promise any timelines. That's part of the reason for the current price. You will have to do a bit of work yourself so this may not be for everyone in this raw form. The timelines on this will depend on what else the design team end up doing. The team is rarely underloaded so this sort thing can take time.
yohan,
some rough edges are not a problem as long as the board has its FPGA bitstream and there is a description of the protocol used to communicate with onboard FPGAs so that mining programs can be upgraded to use your boards.
if, on the other hand, you're selling a "naked" board, without any software nor FPGA bitstream, then this should be clearly stated since very few here will be able to use them even adding a lot of work
spiccioli.
