I don't have a clue what you're talking about, Dr. Brin, but it's good to know you're still findding the time to keep up with brin-l. It's your fault that I got sucked into joining Facebook. Your wall is far too interesting and turning into a time suck!~) _

The idea is straightforward. Alice wants to send Bob a message via an ordinary wire. At each end of the wire, there are two different resistors that correspond to a 0 or 1. Alice encodes her message by connecting these two resistors to the wire in the required sequence. Bob, on the other hand, con
