Just throwing in my 2 cents, i was playing a field in the states, and this guy had a similar rig set up. out of curiosity i asked him about it. he told me he had been experimenting at his college (i guess prof's need to "shoot the shit" every once and a while ^_^) for years to finally get this system working (the one he had on the field)
moral of the story: it took him years under lab conditions (from what he told me) to get a SAFE working system. mind you.. his also had auto fill peak detection ext ext.. if i can find his web page ill post it up.
