downloadable audio books

Downloadable audio books definately part of libraries in the future. The problem as I see it is that subscription services are tied to a particular technology (eg windows media player). In reality there is a diversity of mp3 players out there. For patrons to really embrace it would have to be in an unrestricted mp3 format. I had a look at the project gutenberg audio books. I was to curious to hear what the computer generated audio books sounded like....AWFUL. Really awful.... I don't why they bothered.
