After the game, we headed into John's office to play around with his home control system. Throughout his house are several small keypads with an LCD screen he uses to control the music and lights of the house. The primary controller is a program that runs under Windows and John's idea is to reverse engineer the protocol used to communicate between the two (which runs under IPX).
We downloaded Ethereal [1] to capture and display the network packets but since everyone was pretty tired we didn't far in the engineering aspects.
