I havn't had as much time to work my client code as I wanted, but I finally got around to finishing it. There are some differences with rioplay, the big difference being that I put a lot of control in it's web interface (including remotely navigating the menus). It also supports shoutcast streams, and works against the standard server. I've released the source code as well as the receiver.arf file which you can place in the 'Audio Receiver' directory and try it out. You can find a screenshot of it's web interface here :

You can find the files and notes here :

And it's shoutcast presence is here :

Give it a shot and give me some feedback.
