tracking ball with bluetooth?

[wkosma]

hello,

i`m looking for solutions to track football in realtime during the game.
i wonder if it`s possible to place a bluetooth sender in the ball and couple of receivers around the pitch. then meassure signal strenght and calculate th position.
is there a device which can accept multiple connection and meassure the signal?

i would appreciate any comment or suggestions,

thanks,
wojciech
