Speaking o'wot, any idea what whatermarking Napster's going to be using?

It's apparently vended by Relatable, and utilizes extant characteristics
of sound recordings to identify them.  Appears to be a different beast.
Not sure if DMCA plays a role or not with this.  Would also be
interesting to know what the weaknesses of this method are.  If realtime
(or low-cost) audiostream modification could make this impractical, it's
not going to go very far.  You don't need encryption, just obfuscation.
