I'm interested in setting up a site where I can put MP3 files on my server (outside the web root) and stream them to a flash application. I'm not talking about progressive download here. The basic idea is to let visitors hear a band's music without actually downloading or caching an mp3 or SWF which could be located as a file and saved or ripped.

I have seen this awesome tutorial on streaming an flv and was wondering if anyone can recommend a PHP/AS3 solution which would let me do the same for audio.
