It's that with certain methods of encoding, a piece is entirely worthless without the rest of the file. That is, I could give a chunk to the IP owner to inspect, and there's no way that he could tell me if it represented a part of his work. Surely, even without encoding, the piece is pretty worthless without the remainder of the file. But I see what you mean though (you couldn't even reconstruct a portion of the file). Im not sure it matters; the point is definitely the intent to supply the copyrighted media in whatever form. It's similar to the persons idea not long ago of supplying obfuscated MP3's by encoding them as Tweets and then supplying the code or algorithm to recover and reconstruct the file. It's all part and parcel of the same thing. It's just obfuscating the delivery method not the actual package/intent. More importantly I don't think the court will be sympathetic to the idea; and if that is the case it risks invalidating other arguments you may bring. (there is a similar thing in money laundering; many launderers try and get away with it by rotating very small parcels of money from lots of different batches through legitimate transfers. The idea is twofold; it's difficult to reconstruct the original larger packets of illegal money and b) they can claim, for various reasons, they had no idea of the origin of the money. This argument, as you can imagine, doesn't last long in court :)) I think, ultimately, it is not currently possible to fight the idea that distributing copyright materials in any form could be legal (or at least not illegal).
