We give the floor to Remy:
Rogue Amoeba yesterday released since AirFoil 3.0
This tool is a must-have for any Macuser (or even Windows User, as a Windows version will follow) who uses Airport Express terminal (s) connected to a stereo to broadcast the audio of any application running on the computer.
The main developments of the tool over previous versions are really cool:
1 - now the sound of the selected application can be distributed not only via Airtunes to a stereo connected to an AirportExpress terminal, but also on any Mac with an Airport card in real time , when you install a small application that comes with AirFoil 3 (and start it). The Mac source of course can also be the target of the audio distribution.
2 - AirFoil now includes a video player capable of playing not only any video on the Mac, but also a DVDVideo, disseminating synchronised audio/image via AirTunes.
MacOS X really lacks such a too
