I've independently produced an audiobook edition of my nonfiction book Information Doesn't Want to Be Free: Laws for the Internet Age, paying Wil Wheaton to narrate it (he did such a great job on the Homeland audiobook, with a mixdown by the wonderful John Taylor Williams, and bed-music from Amanda Palmer and Dresden Dolls.
Both Amanda Palmer and Neil Gaiman contributed forewords to this one, and Wil reads them, too (of course). I could not be happier with how it came out. My sincere thanks to Wil, the Skyboat Media people (Cassandra and Gabrielle de Cuir and Stefan Rudnicki), John Taylor Williams, and to Amanda for the music.
The book is $15, is DRM free, and has no EULA — you don't need to give up any of your rights to buy it. It should be available in Downpour and other DRM-free outlets soon, but, of course, it won't be in Itunes or Audible, because both companies insist that you use DRM with your works, and I don't use DRM (for reasons that this book goes to some length to explain).
