Brilliant idea. I have an idea to extend this!

1. A relay to reset the PC like iDRAC/iLO

2. 2 dual pole relay to move a USB flash drive to and from the PC it's connected to, in combination with (1) you could then boot ISOs remotely by dd-ing the ISO to the flash drive and then connecting it to the host PC with a relay

It should be possible for the Raspberry Pi to emulate a USB flash drive using the OTG connection, though I'm not sure if it can emulate a keyboard and a mass storage device at the same time. It would be a very valuable feature for sure.

The kernel at least supports that, through the gadgetfs filesystem.

Alternatively, just use a microcontroller for the USB HID stuff, and talk to it via BT/WiFi/40-pin header.

The GPIO should easily be able to handle doing a reset by connecting with jumpers directly to the motherboard. I guess there may be some circuitry required... I'm not positive on how the standard motherboard pins work.
