is a new Mac OS X-only application which allows you to send audio from any application directly to remote speakers attached to Apple's AirPort Express device.
Airport Express officially only supports streaming music from iTunes. With Slipstream you can now listen to your music in any file format from applications like RealPlayer and Windows Media Player.
The program will be available in early 2005 for an introductory price of US $20.
Let's hope someone will hack a similar tool for MS Windows and *nix users. I bought an Airport Express even with the original Monster cables, but so far haven't even tried to use audio streaming because I don't like to have to install iTunes.
Note: This is not the first time someone tried to circumvent the limitations of the Airport Express. In August we reported
how "DVD Jon" cracked the private keys that the device uses to protect music streams.
