Dan zit er wel een DRM op. Ik vond op het Adobe Forum het volgende engelse stukje voor een eventuele zeer omslachtige workaround:
I am currently running Gutsy and have been able to get around the whole Adobe DRM issue using Wine.
First, I downloaded and installed the latest version found of Wine found in the repository.
Second, I downloaded ies4linux to install IE 6.0 in Wine.
Third, I download Adobe Acrobat Reader 7.0.9 for WinXP from
www.adobe.com. Firefox automatically ran the file through Wine and the install was successful.
Fourth, I went through IE 6.0 to
http://aractivate.adobe.com, signed in using my Passport identification, and requested to install on a new computer. I followed the steps, and eventually it asked me to download a file with extension ".edn". I saved this to my user directory then exited IE 6.0.
Fifth, I opened Adobe Acrobat Reader 7.0.9, via Wine, and opened the ".edn" file I saved in the previous step. Adobe Acrobat Reader then goes through the process and verifies all the credentials. Make sure you have a working internet connection!
My online university provides the course E-Books using DRM PDF files. The whole process is initiated through an "ebx.etd" file (which looks just like an XML file) which Adobe Acrobat Reader uses to verify your identity. I download this ".etd" file, using any browser, and save it to the home directory. Then, through Adobe Acrobat Reader via Wine, I can open this file and the PDF file with DRM will be downloaded and viewed anytime you wish.
Het lijkt mij wel erg ingewikkeld om het op die manier te doen
