Hoorah! I now have streaming audio from my pc at home to anywhere I fancy using Slim Devices SlimServer Software. This is free software you put on the machine that has your mp3 files on, you connect with a mp3 player to http://ipaddress:9000/stream.mp3 and then use a web browser at http://ipaddress:9000 to control what songs, playlists,internet radio stations or sounds are played remotely. (and no I don’t have it streaming across the internet just yet so don’t bother trying it).
It works great and after I told it not to use itunes as the music database it even picked up the new cd that I ripped for Kristen.
