High Speed Wireless for Fencing Strip Answered

I've had the idea of trying to create a wireless fencing system (like what they use in the olympics) for my club, and was wondering if this is possible using AVR's and available (and fairly cheap) wireless tech.

For those of you who don't know what this would entail because you do not know fencing, I would have to have two transmitters acting simultaneously that could send out signals checking for touches on a blade that would be received well within 40ms of eachother (the double touch time for epee). I would also need them to be able to send out two different types of signals (for on and off target for foil and sabre).

I found online a project based off of rfid tech that claims to accomplish this and was wondering how effective this route might be? http://www.worldacademicunion.com/journal/SSCI/SSCIvol02no02paper03.pdf

Have you thought about these trolley security sytems supermarkets use?
A wire in the ground sends out signals, if a trolley comes over this hidden wire the lock for the whells and a siren is triggered,

This is not an easy problem to solve as there is no common clock between the 2 wireless devices so the timing between hits is non deterministic. Did you get anywhere with this?

As an addendum I'd like to know if bluetooth would fit these requirements as that would make an absolutely perfect solution.
