Windows/Mac/Linux (and iPhone/Android): Want access to your complete digital music stash while you're out and about with your smartphone? Subsonic is one way to get it. The desktop streaming server has dedicated iPhone and Android apps for making the phone-to-home connection.
We've previously suggested Subsonic as a nifty way of streaming music from one computer to another through a browser connection. That still works fine, but Subsonic's iPhone and Android app collection connects the dots to another place you'd likely want access to your wider catalogue of MP3s.
Streaming tunes from a home wireless network isn't quite as easy as opening a tuna can, but Subsonic does its best to make it easy. You can use a demo account to try out your mobile app, and if you've got a router that support Universal Plug and Play (UNnP), Subsonic can automatically configure it to accept incoming connections, and even give you a dedicated server name (like johnsmith.subsonic.org) to connect to, rather than guessing your IP address at home. That subsonic sub-domain requires a donation after a free period.
Subsonic is a free download for Windows, Mac and Linux systems, along with many server platforms, and also has a number of apps available for the iPhone and Android, some made by third parties. If you're a happy Subsonic user and have some setup tips for newcomers, do tell in the comments.
