How to integrate Amazon S3 support with audio nodule

I am working on a community website which requires uploading audio files. But the owners cant afford the commercial means and high bandwidth cost. The best way to do it is,I feel, through integration of audio module with Amazon S3 so that any uploaded audio could be put in amazon bucket and retrieve from there to play. Presently media mover and flash videos provide amazon S3 support. But I dont know how to integrate audio module, which I am using for my purpose. I need some urgent help. Please direct me to the best way to achieve this. I have also seen that dashplayer module has amazon S3 support and it also attaches with Audio module. can I do it through this means for putting uploaded audios on amazon s3 server. I need help in one more case: How to show Audio Playlist on users' account page so that when they add any audio to their playlist they could easily play them from their own account page. It would be very kind if anybody could help me do it. I've already wasted countless hours trying to do these two things. Please help!
