iPod Agent software allows you to do the folling with your ipod/computer:
* Transfer songs from your iPod to your PC
* Transfer Outlook contacts, appointments, notes, tasks, and mail to your iPod
* Fetch weather forecasts and put it on your iPod
* Fetch RSS news feeds and make them viewable on your iPod
* Fetch local movie showtimes and make them viewable on your iPod
* Fetch daily horoscopes and make them available on your iPod
* Transfer the contents of any folder on your PC to your iPod
* Copy any text file to your iPod
* Create listings of the songs on your iPod in plain text, HTML or CSV formats.
So if you have two computers at home, and want to transfer your music library from one computer to the other, you can easily download the songs from the iPod using iPod Agent. There are lots of fun little things you can do using this software, but I am sticking with the basics (weather forecast, movie showtimes, and news feeds). Check out the iPod Agent website for more information.
