I would think the simplest canonical counter-attack would be to make a
p2p app that compares diffs in the binary output (efficiently rsync
style) accumulates enough
Is there really that much space for marking? Any substantial number of
marked bits will become obvious in the output stream, no?
Is the watermarking system robust? Is it public? And how long ago has
it been published?
If they are only modifying some bits (in the standard representation),
then

What CR does instead is much simpler and more direct. It tries to cut off
any player that has been used for mass piracy.

When a pirate makes a copy of a film encoded as SPDC, the output file is
cryptographically bound to a set of player decryption keys. So it is

As I understand it, they use such a huge number of bits for marking,
that any reasonably-sized assembly of players will still coincide on
some marked bits.
