As you wont be calling the OS via subprocess, which is about the only 
way to fire up some connect to the sound system, you probably should be 
talking about the pymite issues on the pymite group over at google about 
drivers (i.e. sound drivers), what data types (wav, mp3, ogg) they will 
take and how to pass data to a driver. The

nbed.AnalogOut looks intriguing. Perhaps you can spool a wav file to a port, attach the
analog out to an external amplifier.

Also, perhaps you should be looking atArduino and audio projects.
