Thanks! well, from what I've gathered, and looking at the schematics from the usb adapter I built, there should be no extra hardware needed for pwm, as the pic on that board just drives 2 transistors for 5v (which I think is what the arduino digital pins are, no?). I've also gathered that pwm at the physical layer is a balanced bus of +/- 5v in reference to each other. I'm still trying to get my head wrapped around it, but it's comforting that we should be able to do it without extra hardware.
