Try using "AirSnare". It can be setup to automatically 'message' any
unauthorized MAC address when it appears on the network. I setup a
dummy network on a slow weekend just to see how many of my neighbors
I could catch. The answer was several dozen in the first week, and
then my interest waned and I dismantled it. AirSnare is a free
program. Here is an interesting review:
