It seems to me if these devices really have been perfected that the CIA and other super-snoopers have probably figured out a defensive device for it. For example, I can imagine a transducer atttached directly to the glass vibrating it at a beat frequency to the one on the other side, causing any sounds detected to be modulated improperly. White noise tends to mask sounds, too, so maybe the transducer would vibrate the window with a complex UHF/white noise. Or maybe Dow-Corning has developed a vibration-free glass... -- Gary Benson * John Fluke Mfg.
