D'oh!

What happens when a wireless security class discovers a wardriver, just outside the window? (heh)

How about, the SSID of the AP in the classroom gets changed to "we-see-you-in-the-car" and a ping storm is sent through the AP so that it "sticks out" in whatever listing his tool has. Then get a half dozen or so in the class to stand in the window and wave/point.

Okay, we're having too much fun.
