I thought about it - that's why I said "at least difficult" rather than
impossible. In fact reading may not be too hard, but writing is a 
different story.
Since the device requires almost no hardware and all the programming is 
done on the AVR side, it is easy to experiment. I mean the prototype 
doesn't even need to be connected to an Apple - just a serial channel to 
a PC or a Linux box.
