MyTunes RSS – Streaming audio to your devices
Who says you need Airtunes to stream your audio to browser enabled devices on your network?
Enjoy all the songs in your iTunes music library on any device that has network access to your iTunes computer.
MyTunesRSS is a application for configuring and starting a server. You can access this server with any web browser, search your iTunes music library and create an individual play list. The play list is published as an RSS feed with the feed items containing links to the music files. These files are served through the server as well.
The ability to stream audio via any browser enabled device sound almost dreamy.

I have been using this application for some time now and it is really what I had been looking for. Much better than the other solutions I tried. And what is even better: have a look at their official forum http://board.codewave.de. They are already working on version 2.0 which will allow you to browse your library. This sounds so good. I guess I will love it! BTW: support seems to be good as well.
Hi.
I am the codeveloper of MyTunesRSS and I am very happy to see one of my favorite sites reporting about our little up. Wa are actually working on version 2.0. This version will allow you to browse your library, create playlists within the app and stream the music by rss AND m3u-playlists. M3U-playlists are supported by almost every media player. The new version is nearly finished and should be released within the next one to three days! Meanwhile, you can check out some preview screenshots on our forum (http://board.codewave.de) in the developer news section. Also you are allowed to leave some feature requests for future versions.
Greetings,

Sorry, make that a week or two! :-)
