Safaribooksonline DRM vulnerability

There’s a bit of a DRM vulnerability in how the new is implemented. Disable javascript and set your user agent to MobileSafari (very easy to do in Safari once you get the Develop menu enabled) and you can copy blocks of text from the books on your shelf. They do go to reasonable lengths to convince you not to do this though: first there’s a user agent check and second there’s a decent javascript check which measures screen width and height.
