Default audiobook player for the cloud?

having most of my stuff in the cloud, music, videos, documents and so on i had a though "wouldn't it be nice to have your beloved audiobooks in the cloud too Hampa?" "yeah it would if I could find a player with resume, a sleep timer gdrive and dropbox integration" been asking around with no answers, been in contact with a couple of developers well it was mostly a one way conversation I'm afraid. so as I lay here on the verge of sanity (not really, already past that point years ago) I turn to the place I know has the most dedicated crowd, kick ass developers and general people who likes a bit of flattery. is there an app that does what I'm asking for?
