VibeStreamer: Remotely stream your music library
There’s many different solutions out there that give you the ability to access and share your collection of music over the net. Many of them of work, sort of. It really depends on how you want to present your music to the user and how much functionality you’re willing to give access to. In this case, I’ve found a fairly self-contained music streaming server that gives you access to your music through web based flash player, with a login system to boot.
