SDMI (the “Secure” Digital Music Initiative) offered hackers ten grand if they could break SDMI’s proposed music protection technologies, so they did. The entertainment industry has a lot to learn about encryption. I doubt that it’s possible to build a system that will protect content but at the same time allow it to be played on millions of players built by various manufacturers. Either people will crack the system or graft something onto the players that allows them to extricate the content and store it in an open format.
