I use ABS to host my audiobooks and I use the Android app to download them to a folder, and then use Smart Audiobook Player to play them. It works great, though you lose the time syncing with the server, if you care about that.

There are also alternative clients, like Lissen.

Same here. I do this because ABS android app would not accurately track my listening progress, and is very frequently off after a pause. May be off by 30 min, by an hour, gets rather frustrating relistening the same segments. Was never able to solve this.
