How hard would it be to write a script that can play two media files simultaneously? Can the built-in player even support that?

I would really like to develop a Rifftrax player for XBMC, which imposes three technological hurdles:

• I have to be able to play two media files simultaneously (overlaying an mp3 on top of a movie file or DVD playback)
  
• I have to sync the two (using initial offsets and maintaining them by duplicating all user input to both streams)
  
• I have to control the volume level separately (because the Rifftrax mp3s are about 20% louder than a standard DVD audio track)
  

I realize that's probably not possible in script with functionality currently exposed to Python, but I would really appreciate it if someone who knows the media player could tell me if it's even possible in the engine.
