It’s getting pretty common to have all or much of your music on a hard disk. This in theory makes it possible to do all kinds of nifty things with it. One nifty thing is listen to it remotely. It seems obvious: if your computer is online, and your music is on your computer, you should be able to get at your music over the Internet. But how?
If you use a Mac, the answer is simple: MP3 Sushi. This is actually a bundle of open-source Unix tools packaged up with a nice Mac interface. It sets up a music server you can access over the web, with handy features like live downsampling of high-bitrate music, creating m3u streams, etc.
I’ve got a fixed IP number, which makes it a little easier, but there’s a solution for dynamic IP as well.
My music is online, but is hidden behind a password to limit access. Ask me if you want to listen in.
