Alvis Dark writes "Apple launched iTunes Plus earlier today, the fruit of its agreement with EMI to sell DRM-free music. What they didn't say is that all DRM-free tracks have the user's full name and account e-mail embedded in them. Is this to discourage people from throwing the tracks up on their favorite P2P platform? 'It would be trivial for iTunes to report back to Apple, indicating that "Joe User" has M4As on this hard drive belonging to "Jane Userette," or even "two other users." This is not to say that Apple is going to get into the copyright enforcement business. What Apple and indeed the record labels want to watch closely is, will one user buy music for his five close friends?'"
