> H3: MIDI could be a separate browser, play sounds, and communicate through SAI to an X3D browser using conventional events for animation.

H4: a hyper-browser that owns the main loop, time, rendering buffer, and viewpoint/camera and works as a plugin platform for other browsers -x3d,kml/collada/...- would also support a MIDI browser plugin, so when rendering all technology layers are rendered.
