Looking at the "technology" page it is clear that this has no effect on
CD to CD copying (as one would expect).

The "technology" appears to work by causing similar artifacts to that
which occurs by transcoding. In fact, this may as well be (and indeed,
probably is) simply a closed lossy codec.

If I wanted to protect music from reencoding, this is how I would do it.
The net result is something pretty useless. I certainly wouldn't buy a
CD I couldn't rip and encode (and it wouldn't be to share). If I buy a
CD, I want a 16bit 44kHz PCM representation of the original master, not
after a version that has been through a psycho-acoustic mangler.
