Mental constructs like this one, complicated schemes that require knowledge of modular aritmetic to understand, is why this will not happen. Whatever aspires to replace paper cash for purposes where paper cash is a must (in real life, conferences don't count) has to be as simple to understand, verify and manipulate as paper cash itself. Flipping bits in the gates or on the wire is not that - unless Joe the Hitman or Gordon the Dealer or Jeff the Cleaner can well understand it and in addition to that have implementor's balls within reach if something goes wrong. ===== end (of original message) Y-a*h*o-o (yes, they scan for this) spam follows: LAUNCH - Your Yahoo!
