Oh, and a suggestion that might be helpful to you for revision 2:
Consider adding an 8P8C/RJ-45 jack to your PCB so it is modular.
That's exactly what I'm planning to do.
Greg Ercolano is making a solid state 1A2, but he is intentionally using discrete logic instead of microcontrollers so anyone could build it. Micro's are awesome, but only if you have the means to burn them. He could just sell the boards and a parts list and anyone could assemble one. Heck, I'd buy one if it was like a DIY kit that had the bare pcb and a bag of parts. I love soldering stuff up like that.
