Again, breaking the DRM is not illegal. It's not. You can do it, I can do it, he/she/it can do it. Whenever, wherever, and however you like. You can do it with a shoe, you can do it with a canoe. You can do it in a house, you can do it in... Alright, I'm getting carried away.Tsyr said:2) Break the law and remove the DRM encryption. And as many others have pointed out, this is NOT HARD. If you understand exactly what DRM is and how it protects the PDF, you dont even really need to go find some shady hack... There are legit (As in, there is a good chance you have the stuff on your computer already, if you do PDF publishing or the like) ways to do this already. (No, don't PM me asking me how, I'm not going to tell you.)

What you cannot do is share the cracked file. (And even that is shady, as I can buy a physical book and give it to a friend - legally, a case could be made against all this hubub saying sharing is illegal. But that would take money - that's why the RIAA only sues poor kids and old people. Let's see 'um sue a lawyer's son or someone with enough income to blow some on principle.)
If there's a PDF you want, buy it. If it's protected by some ignorant scheme, crack it. Then use your file however you want. As long as you don't actually give it to anyone, you never enter the grey area - thus no worries.
