myTunes is a donationware program written in JAVA and runs both on Mac OS X and Windows with your iTunes. It acts as a small webserver which creates RSS2 feeds with enclosures (aka podcasts) from your iTunes library and even from each of your playlists!
For what do i use it?
I use it to stream my iTunes Library across my wireless LAN to my Sony PSP to listen to my music while walking around in my house 🙂 It’s really great for that purpose because the webserver fits nicely into the PSP screen, is easy to navigate and you can even search for songs or artists! I really like this piece of software – give it a try.
