Hardware progress

Using my handy triwing screwdriver I opened the Nunchuk attachment. Consulting the pinout from wiire.org, I soldered wires onto the Clock and Data lines. I attached my oscilloscope and confirmed a 250kHz clock rate, but my 'scope wasn't sophisticated enough for me to read the bits manually. I bought an Arduino from SparkFun; I was hoping to use the Wire library to sniff the may-or-may-not-be-I2C bus. I have seen some signs of life, but no actual data yet. I'll also try this simple approach using only the parallel port on my PC, but it does specify 100kHz on that page, so it may not work.
