Gaiman on MP3 Audio Books, Mirrormask

A reader writes: "It appears that Neil Gaiman released two of his books (Anansi Boys and American Gods) as books on CD. The interesting twist is that they are being released as MP3 - which for the world of audio books is something pretty new. ". Indeed; MP3 audio books, I think, have given the book publishers the willies because of the DRM issue - anyone else seen this before? And also worth noting that Mirrormask was released in motion picture form and rocks. I think to describe it would be equal parts The Dark Crystal and Myst, combine with Carnivale and a dash of The City of Lost Children.
