Another quick idea (that I discussed with friend Ben Morris today).
Go to this page and simply search for any topic that’s on Wikipedia - and then download the entire article as a sound file to your iPod!
I made a short example about Alfred Nobel HERE. It’s in mp3 format. The info is from Wikipedia.org and the soundfile from Wyhiayg.net. The text-to-speech engine is perhaps not the best, but I’m sure someone could find a better one.
OK. Anyone interested in doing the coding? We could surely get a million visitors a month?
