There is plans for official audiobook support in the Music Library, the code hasn't been merged yet and will probably be only very basic support at first.

That sounds great..
The one feature that is sorely needed is bookmark and being able to continue at some later point even if the system has been shut down.

The coming audiobook supports includes resume, not sure about bookmarks, I've asked if there's the possibility that the resume could be later expanded to cover music files/playlists.
