Another excellent point. Though I suspect that the book-buying public won't stand for it. We're already starting to see less DRM in the online music market, with Yahoo recently taking a stand against DRM for its online music store. I think eventually content owners will discover that they actually make more profits when they don't irritate willing customers. The key is to offer sufficient incentive to discourage unauthorized distrituion. While tech-savvy folks will always find ways around having to pay for bits, the general public has neither the means nor even the desire to do so. As long as they can get what they want for a reasonable price, they'll pay it rather than having to bother with it.
