I just discovered (and tried) this wonderful piece of software
It allows remapping your keyboard in many ways, and it's controlled from a simple configuration file (so, you can prepare one for your disabled friend).
You can, for example, remap the keyboard to only use its right half, if the left hand is dysfunctional (similar to the mirrored keyboard I made, github.com/clackups/qmk_firmwa… ).
Also, it should be useful for #disabledgamers , to map, for example, AWSD to different keys.
