I think you could make some of these commands set/get :
/deck/volume  ===> return volume (get only)
/deck/volume 0.5 ==> return volume (0.5) (set and get)

I plan to have all my methods work this way.

Enabling

/deck/  ===> "play!, pause!, stop!, cue, eject!, load!, volume"

would add auto discovery of methods (I do not know if the "!" is  
allowed, but it would indicate an "action" opposed to parameter  
setting).
