Re: Tied into Amazon's ecosystem?
"Obviously is over your head as Calibre will not allow drm breaking plugins to work with their software and go to great lengths to maintain this stance ;)"
I think you'll find that's not true - it only takes a little Google search to easily come up with plugins of this nature that work with Calibre. Now, Calibre may not support them - but that's something different than saying working plugins don't exist. Now, I'm not sure about Amazon's DRM specifically - but I believe you can find those too if you look around enough, and aren't too concerned with officers of the law knocking on your door.
