Switched from audible to libro.fm and Thalia.de . Yes libro is still US but you can select a local book shop that gets a share of your subscription.
The crazy part is, in both cases you actually download mp3 or even m4b files that you can save on YOUR system.
Guess why I am so happy to get m4b files from libro :D For getting my audible files I used libation. Thanks anyway :)
