I'm not trying to put words in your mouth about sharing copies (hence inherit, not borrow or get a copy of) - my main point was that while: >> I would just consider having your own drm free backup. > You bought the book, you own the pdf. seems perfectly reasonable on the face of it - it implies removing the drm - which I think is still unclear if it is legal or not (per the dmca)? I believe there was some case around backing up dvds (a notoriously fragile medium) - as well as circumventing drm in order to view legal copies (eg: play dvds on Linux/in vlc) - but I'm not certain if that was tested in supreme court or not - and if it would apply to ebooks. I do know that with the initial draft of the dmca, circumventing drm was in and of itself illegal.
