Dear Group, I believe that I see a potential serious problem with they onset of truly unbreakable anonymous communication combined with untraceable digital cash. The problem is that crimes such as blackmail and extortion would become absolutely impossible to defend against. Kidnapping for ransome would get a LOT easier. One of the serious deterrents to crimes such as kidnapping is the probability that one will get caught attempting to communicate ones demands or collect the payment. If one can make TRULY anonymous demands and receive payment which is TRULY untraceable, one can strike without warning and then proceed virtually without risk. I could send you an anonymous note threating to poison your dog, kill your wife, burn down your house, whatever..., ... unless you pay me $$$ in untraceable digital cash. What can you do? You pay and I go my merry way with your money, or you assume I am bluffing and don't pay. MANY PEOPLE WILL NOT CALL THIS BLUFF, and there is the serious problem... I foresee a great way for jerks to "earn extra income in their spare time" threatening hundreds of people in mass anonymous mailings. Some of these folks will be scared enough to pay off. Where is the risk to the person who commits these acts? He's COMPLETELY anonymous! Food for thought. Dorn
