Ed Felten : DRM, and the First Rule of Security Analysis:

If you’re a copyright owner, you have two threat models to choose from. The first, which I’ll call the Napsterization model, assumes that there are many people, some of them technically skilled, who want to redistribute your work via peer-to-peer networks; and it assumes further that once your content appears on a p2p network, there is no stopping these people from infringing. The second threat model, which I’ll call the casual-copying model, assumes that you are worried about widespread, but small-scale and unorganized, copying among small groups of ordinary consumers.
