I've being experimenting with different level of compression with the speex codec. And I've made a 2 hour 59 minute copy of Alice in Wonderland take 11.5Mb's of space (which can be further compressed for storage in a .tar.bz2 at
9.7mb's) The quality of the audio, while not perfect is perfectly listenable to (the size can be further reduced but I have found this size the best trade off). Here is a .spx file as a audio sample <a href="http://www.sendspace.com/file/6vgpmc">

</a><br><br>The audiobook is made from <a href="http://librivox.org">librivox.org</a> which releases publicly read audio books into the public domain. They have numerous other children's books and short stories, which I'd be happy to compress down if it would help the OLPC library.
