Slashdot linked up this interesting bit of news about a theme park in Florida (no, not that one) using RFID tags embedded in wrist bands to help you keep track of your group as it roams the park:

Visitors can locate other members of their group by using touch-screen kiosks throughout the park that are linked to the system, called SafeTzone's Real-Time Locating System.

The dot-heads are predictably up in arms about "big brother", but personally I think it's a pretty neat idea. Ellen has always had the ability to teleport across a store when my back is turned, and I'm sure Olivia will inherit this talent. Avoiding the spot-by-spot search would be very nice.
