I've been considering reading things aloud.
Always wonder about the fair use issues though.
It's definitely interesting on two points!
1 - You're changing the format from print to audio
AND
2 - You're changing the distribution medium from paper to digital file or optical media
Either one of those can be problematic!
Think about all those libraries with VHS collections that cannot be simply converted into DVDs despite cheap access to both the tools and media with which to do it!
