+ The high-level design is as follows:
+ 1) Connect to the PulseAudio daemon
+ 2) Watch for the creation of new audio players connecting to the daemon (this includes ALSA clients running on the PulseAudio emulation layer, such as Flash plugins)
+ 3) Examine any new audio player's PID to see if it belongs to our own process
+ 4) If so, tell PA to adjust the volume of that audio player ('sink input' in PA parlance)
+ 5) Keep a list of all living audio players that we care about, adjust the volumes of all of them when we get a new setVolume() call
