But, sadly, my skills don't extend to much more than a surface level analysis.

That said, it looks like the Readium #DRM is reasonably inoffensive. Once you have the file you can back it up and move it anywhere - you just need the password to open it. No network connection needed.

Tondelier a jeté un pavé dans la mare après le prix décerné au député RN Tanguy par le "jury" du Trombinoscope à l'Assemblée: "Vous (les médias) avez un pouvoir immense.
