Scientific American article about how the DMCA act is screwing things up for computer hobbyists, traditionally a great font of innovation:
AiboPet [handle of the hobbyist] violated that copyright when he cracked the robot's source code to reverse-engineer software that allows Aibo owners to teach their pets to dance, speak, obey wireless commands and share the color video that serves as their vision, among other things. None of the programs are usable without Sony hardware and software. They earned AiboPet no money. He never revealed the encryption code or the program he used to defeat it. Still, because the DMCA makes it illegal to break any encrypted digital code, AiboPet's actions made him a criminal. The fun began when Sony decided to treat him like one.
