the guy who wanted it done had contacted me. But it may not work out as he is trying to move from California ot Missouri, and he hasn't given me a lot to work with. He thinks a Linux driver can be written without first having the hardware to write it on. Getting a box with double throw relays on it has been impossible to find. I will have to find a normal embedded Linux box with an expansion card, and then get an Electrical Engineer to design the card and then get the specs to write the Linux driver for it.

Keep in mind that the client may change his mind and go with a production house instead of me, he has so far halted all work on it until he can meet with me, because I cannot find an off the shelf solution with relays built into it.
