-  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
