Kezza: I also like PDM's content protection structure. It protects the books using a registration code that is freely available to the registered user, but that the user at the same time does not want to release. It makes me able to read books I have registered on any device I choose, including multiples of my own, while at the same time preventing their distribution en masse by registered users. Considering that PDM have doubled their sales, I believe to 1.6 million eBooks sold for 2002, they must be doing something right.
