hmm. i have developed an io/adc control/logging (read/write) to/from the pc for my arduino mega. if anyone interested, maybe i can publish it, or is there links for such similar thing? sadly its in asm.
edited: i just saw the doc halfway and i can say its a very good documentary. not only it tells about arduino, but show some stuffs/projects, who got involved, and most importantly, how open source hardware idea evolved. thanx for posting.
