So this post has some good information on a product called Ipod Agent.  It essentially lets you have rss feeds displayed on your Ipod.  It also lets you sync your outlook information as well.   I've tried this stuff out, but IMO the Ipod display was really not meant for text.

The ultimate “Ipod Agent” would be one that takes your information and converts it to computer spoken MP3 recordings using some of the ATT natural voice technology.  Then you could use your Ipod, as it was designed, to listen to your favorite RSS feeds and new mail.  Does anyone else think this would be the way to go?
