#VoiceDream apparently now has beta Kindle support in the main app, i.e. a beta version isn't required. There are reports on the mailing list that you need to be a subscriber to see it, that there should be a "Kindle beta" option in the "Settings" menu, and that you can't lock the screen or background the app while reading a Kindle book. I subscribed and updated the app, but it isn't showing up for me, so I don't know any more than that.
