Users of iTunes are now able to share their music library with the world, thanks to a free application called Dot.Tunes.

The application turns music libraries into SQL databases, allowing friends with a password to stream on their own computers. The application includes an AJAX-based browser and "multiple layers of security," but all users need to know how to do is download and install the program, according to Wired's Listening Post.

The company was originally selling the app for $30 per download, but it is now free, with charges for plug-ins that give the app added functionality. There's a $20 plug-in that allows users to stream music on their iPhones and another on the way that will do the same for the Nintendo Wii.

Australia-based Dot.Tunes is pushing the software as a simple way to publish radio shows, TV programs and music mixes instead of paying to podcast or for radio streams. It also offers an RSS feed that lets subscribers know when there are new additions to a library.
