traceable keychain

miniature battery powered keychain for traceablity by radio frequency
  [vote for,

A keychain that emits specific radio frequency with a small built in buzzer also. Comes with a centralised control box that will activate the keychain's buzzer with a selectable button (to choose which item you want to locate). The range of the centralised control box to the keychain will be 100m. (more than that, the buzzer will be redunant) Usage: bunches of keys that are usually misplaced; cameras; PDA; etc... (anymore ideas for usage?)

       I'm quite sure this has been mentioned before, but am still amazed that no company has taken this up yet. Perhaps the reason is related to the secret chips they put in license plates...

       Great idea, but very baked. See link.

       A cheaper version of (what-have-you) isn't going anywhere.
