JustePort streams audio to an Airport Express

It seems like Jon Johansen can barely let a month go by without releasing something exceptionally useful. This month, he figures out the encryption that iTunes uses for streaming Apple Lossless audio, thus theoretically allowing any application (on any operating system) to send audio to an Airport Express. JustePort is his little command line tool that does just that. It works, too, as long as the file is in Apple Lossless format, though it uses twice as much CPU as iTunes (and that's even without the realtime lossless encoding).
