Rhythmbox needs a way to stuff plugins for various things between the decoding 
and the audio-out part. This is not hard - it's in fact pretty easy or it 
wouldn't already have been done for the volume control. The hard part is 
getting it right inside Rhythmbox and/or providing a plugin mechanism for it, 
so people who don't want to / can't use visualisation (goom takes insane 
amounts of CPU power) have a way to disable it, and everybody using it has a 
way to resize it correctly, display the right plugin and whatnot.
