The more one studies computer science, the less one believes that information can be owned in any meaningful way. I remember reading a paper on a "lightnet" that basically XORed arbitrary blocks of data together, then produced a recipe on how to recover some original data by XORing the appropriate blocks. With just this recipe you could ask other nodes for the random blocks, then recover the original data locally. The paper made a good argument that however you try to define ownership of a block, it will lead to some contradiction. The system was implemented but I can't recall its name. I think it was hosted on SourceForge.
