1. broadcast headset
2. load static data
3. run simulation

 acceptHeadset # headset found by CCU
 # transfer game-specific graphics upon startup;
 # may want to load init  data in via wired usb
 # connection
 loadStaticData(image ID, 2D/3D image)
 # headset can start rendering frames
 startSimulation
 # possibly one packet for each  2D and 3D images;
 # implicitly creates memory for new image instance if not exists;
 # in addition to overlaying  HUD images + 3D objects, may want to
 # add 2D textures in 3D environment.
 updateImageInstance(image ID, instance ID, location, orientation, hide/show)
