heh. There's a note in the ps2dev library (which allows an arduino to emulate a PS/2 keyboard) that there's some possible incompatibilities with the PS2Keyboard library, which allows an arduino to act as a keyboard controller.
because of course. why not have two arduinos talk to each other by pretending to be a PS/2 keyboard and PS/2 keyboard controller?
I should build a network out of this.
