The guys at Aimster are using judo against the record companies by protecting themselves using the DMCA. Basically, they’re encrypting their communications so that if the record companies attempt to circumvent that encryption, they’ll be in violation of the DMCA — a law that recording industry wanted very badly. I wish we could come up with more ways to bludgeon industry with the consumer-unfriendly laws that they’re always spending big bucks to get pushed through Congress.
