At the moment DRM on e-books is usually so annoying that there are good economic reasons for not doing it. This may change with the rise of handheld books.
Personally, I would embed the user's name in e-books, and explicitly invite them to share their books with 3 friends.
Simultaneously, I would go after file sharing sites - especially the smug ones claiming to be online libraries circumventing greedy publishers and authors etc - using ninjas or possibly Serbian mercenaries in such a manner that my name would supplant that of Dracon in common usage.
