Sorry, Nick, but there's a difference between watermarking an audio or
image file (to identify authorship) and trying to restrict distribution.
Besides, if you're really looking for paranoids about restricting
digital content, forget Apple and go visit Sony. ;-)

Are you looking at an open operating system to help you close your
mind? Forget the technical issues involved, I personally think you are
talking to the wrong community: watermarking is a means of restricting
distribution of visual material.
Linux is not about restricting distribution of anything.
Perhaps you should raise these questions on one of the Apple mailing
lists where you will meet equally paranoid minds. Bringing these issues
up on this list is out of line.
