No, I understood this. In a later post it was brought up that this is
essentially watermarking your content with a unique ID, which can be
bad for P2P tracing purposes. So I was suggesting that by using a
set of 'watermarks' one could avoid essentially embedding a
unique label to one's copy of some content, at some cost in Cycles.

True. But I've found some manual intervention to be required anyway,
sometimes you find a few copies of the same content stored as
files due to slight differences in naming or truncation.

It was disturbing that, as the bottom fell out of telecom, and handsets
commoditized, faceplates and ringtones were highly profitable.
