The funny part is that you don't have to "crack" anything. The PDF standard
is supposedly open, so Tom, Dick, or Harriet can write a PDF viewer. The
viewer obviously has to be able to "decrypt" and render the document onscreen.

So it boils down to whether the viewer software honors a little flag requesting
"please don't print me". For any non-copyright-infringing use, I'll write
whatever software I want, thank you very much. Or modify the source to an
open source PDF viewer, and recompile. No "cracking" is necessary :)
