well, I suppose if you're going to go the microcontroller route you may as well
make it an external unit with the serial controller included... no messing
around with custom drivers on the host system then. Bit beyond me though I'm
afraid, but as the original poster said I'm surprised nobody's done it,
especially a hobbyist...

I suppose it'd need its own power supply though which is a shame.
