Sounds good to me... I've built an empeg kernel but never gotten to play with iButtons. I've wanted to ever since I first read the web page on them, however. There's always the microphone input on the docking connector which is looking like it will never be used. If there's already a one-wire interface on the empeg, is there any chance that we can get to it? Otherwise, a serial converter appears to cost $5 and wouldn't void the waranty. I'd love to have an interior/exterior thermometer display, which would also be possible. I don't share my car, so ID isn't too important for me...
