I want to try it today, with the book I initially bought. Since buying it I've downloaded it from a different place, and even if Libgourou works, will probably not go back to buying DRMed books.
Not that used to compiling stuff myself, wasn't able to get Libgourou working yesterday, but I'll try today :)
EDIT FROM MYSELF: I think the .acsm which the shop gave me is broken. There are some sample .acsm's from Adobe which I've tested, and they work. But not the book I actually bought.
I gave DRM a chance. And similar to movies and shows, torrenting or other means seem way more usable. Time for the pirate hat, arrrrr.
