I picked this up as part of Humble Bundle Freedom Bundle, whose offer expires in about 15 hours. Since it's Doctorow, you should be able to get at least the ebook off his web site if you're interested (not sure about the audiobook itself).
So far it's really interesting, and I'll have to remember some of the analogies he uses. There's a lot about how digital locks protect middlemen rather than the author of the work. Actually, just read it.
