On Over-the-air encryption... If anyone wants to read Tom Clancy's latest book, _Clear and Present Danger_ about a set of covert operations against drug kingpins in South America, they will note that he mentions a magic box that will scan the airwaves for voices on the cellular channels. This allows the protagonists to follow the conversations of the kingpins as they hop from limo to limo using a different phone with each conversation. Does TriggerFish do this? My theory is that the 260-bit repeated XOR code was proffered because it wouldn't interfere with algorithms that were doing simultaneous voice recoginition. It is, after all, just the equivalence of doing a discrete convolution across the signal. I believe that this should be easy to handle with a few clever signal processing algorithms designed for noise reduction. I don't know this with any stretch of confidence so I would like to be disabused of this idea if it's harder than all of that. --Peter
