146531 Secure Flash MP3 Player

I am looking for someone to script a secure Flash MP3 Player that will not allow the mp3 file location to ever be revealed to the visitors or allow the file to be cached. If they attempt to go to the path that song is streaming from, I'd need it to re-direct them to a 404 page. I already have the design made up, I just need the scripting to be done in the correct way in order to safely stream mp3 files without the fear of visitors caching it or being able to go to the direct source file. Thanks.
