From the outside looking in, the contents of data you provide to the cluster is cryptographically opaque. Unless they can prove you have the cryptographic keys to access a particular piece of content, you can make the argument that you literally had no way of knowing that the encrypted data you are storing was in fact pirated content. > With this in mind, ask your testers to participate in a challenge: they use > it as normal, but offer to pay $100/instance to anyone who can prove a given > IP address pirated something -- a crowdsourced RIAA simulator.

Provided you can obtain the encryption keys, you may be able to prove that a particular file is, in fact, infringing on a copyright. However in order to prove that participants in the network actually engaged in an act of piracy as opposed to merely providing nodes which engage in the free exchange of encrypted data, you would also have to prove that a particular user also has the encryption keys needed to access a particular piece of content. I think this would complicate prosecuting users for copyright infringement, however IANAL. -- Tony Arcieri
