I just found radical piece of software called AirFoil that gets rid of the obscenely offensive restriction of allowing only iTunes to access your AirPort. AirFoil allows your wireless speakers to play sounds from any application on your computer!!! I have been blasting tunes all day long. Down side, after ten minutes of play, AirFoil adds an ugly hiss to your songs unless you pay 25 bucks for the software. I have found a mini-hack. If you just keep pressing the speaker button on the AirFoil interface it resets the hiss timer to another 10 minutes. If you know of any other software that does this, please let me know. I love my AirPort Extreme!!!http://www.rogueamoeba.com/airfoil/
