A friend of mine in Perth Australia just got caught by some random bluecasting waiting for a bus. The effort was for Big Brother, which had installed advertising in bus shelters that had built in Bluetooth transmitters. If you happen to walk by and have your Bluetooth powered on your mobile you receive an SMS saying "I'm watching U, Ur at X" and the "X" was personalised to reference the exact corner of the bus stop (very clever and creepy). Then another text shows up answering the "what the hell" question in your head - "Big Brother is Back on Channel Ten." I'm not sure who thought of this, but a big hats off to a very appropriate way to harass people via Bluetooth, but in a very entertaining way. Hopefully consumers aren't being charged for those text messages, could upset some people but hopefully they'll just relax knowing that big brother really isn't watching them, or is he? :)
