> Right, the question is, when my computer requests a file from your computer, which one of us is "making a copy" ? It becomes less ambiguous to ask who is doing the publishing.

That question is irrelevant in a discussion about legality, because it doesn't matter who physically made the copy at the time of transfer. It only matters if the first party has the legal rights to distribute it, which they don't. Since you are knowingly taking possession of copyrighted property that they don't have the rights to, then you have now violated the copyright by obtaining an illegal reproduction.

Just because you don't get arrested for purchasing a bootleg DVD, doesn't make it legal. Not all illegal things involve arrest or prosecution. Lots of illegal things can only result in civil lawsuits. This is one of those things. The reason the seller of the bootleg DVDs can be arrested, is because the cities where bootleg sales are most common have laws specifically targeting the advertisement and sale of copyrighted works that were reproduced illegally. If you buy one, you're still violating the copyright and the MPAA could file a lawsuit if they had any evidence of your purchase and felt it was worth their time.
