I wanted to use a WRAP board to remotely control a couple of PC's (where "control" means "reset" and/or "power on/off"), so I constructed a a small board with opto-isolators which fits inside the WRAP case and connects to the LPIO connector on the WRAP, with a wire to connect internally to the 'reset' and 'power' pins inside the PC. I then did some simple software which sets up the connector (i.e. changes the control register bits) for this use, and directly sets the appropriate bits in the GPIO register (i.e. no driver or interrupt handling required) to (remotely) accomplish it's functions. It's all installed and working, allowing me to "control" a system in San Francisco from here in Hong Kong :-). If anyone is interested, I'd be happy to share the circuit details, and perhaps take a photo of the board.
