Stream and download plugin

Hi – I haven’t been able to find a plugin that will let me offer downloads for (registered) users and a streaming option.

What I want to do is let people stream an mp3 version of some music, before they can pull the complete wave file.

I found wpdownloadsuite – it’s halfway there … but sadly I wouldn’t be able to hack it.

So I’m hoping someone in this friendly community might be able to point me in the right direction.

Sry if this post is redundant, but I dont get much out of searching for download, stream and such.

Thx.
