Unfortunately I can't post in any other area yet !

As for the Software I have it ready to go already via this topic.  https://bitcointalk.org/index.php?topic=137934.0
And as it will use my Raspberry Pi to run up to 4 FPGA boards I think it could be cost effective on the electricity usage anyway.

I just need to find some well priced and proven FPGA boards.

The asics are yet to be proven or shipped as far as i can find out. !

Rat.
