Found this YouTube video via Lucacept.
And Lucacept's discussion about the issues facing libraries lending files (e-books, audiobooks) is most relevant and not, at present, finding answers from publishers.
Watch the video on YouTube here if you the one above doesn't work for you.
It's a brilliant video. Brilliant. Bravo DK/Penguin USA.
PS. And the format of this strikes me as having possibilities for writing, too.
