Wardriving: you can look, but don't touch
Wardriving --the practice of driving around with a portable computing device and Wi-Fi antenna, looking for open Wi-Fi networks--is not new. In fact, wardialing, or calling up random phone numbers looking for modem connections, has been going on for at least 20 years. There is, however, a new ethical debate surrounding wardriving, whether it's legal, and whether it serves a larger purpose.
