Based on what I've heard so far it seems like for 2008OS it will go something like: 1) Edit /etc/bluetooth/audio.conf and uncomment some line 2) Pair your headphones/stereo 3) Install Kagu 4) Launch Kagu and click its Bluetooth icon 5) Hit play and music comes out of your headphones/stereo I don't know if it would be frowned upon or even be all that smart but it seems like someone could just make a package whose entire purpose was to update the configuration file in question. So that first step might be "install enable-a2dp.deb" In 2008OS it should be much easier for applications to support A2DP, but it's not enabled by default.
