Sony "rootkit" CDs had designs on iPod

The Princeton researchers that have done much of the work deconstructing SonyBMG's recent controversial copy protection software have found an interesting new tidbit. According to their new findings, the Sony software had a hidden component that could convert songs from the CD, or other ordinary MP3s, into a file compatible with Apple's copy protected FairPlay format.

That would mean that the songs could be played on iPods, which hasn't been the case with copy protected CDs in the past. It apparently accomplishes this by using open-source, yet copyrighted code, a practice deemed a no-no in programming circles.

It's not yet clear how this came about. Record labels have hoped to establish compatibility with the iPod for their copy protected CDs for some time, and EMI Music has even said that its CDs are close to reaching that point. Apple, for its part, denied EMI's contention.
