I stayed in a Hyatt this week that charged a wireless Internet connection per device as opposed to the usual room charge. This was really irritating as I had my work PC and iPad with me, didn't really fancy paying $35 a day to get both on the Internet.

So, how does the hotel track device? I'm guessing it's by MAC address so if I downloaded one of the numerous utility that lets me spoof my MAC address on the laptop, could I have got around this?
