Another nod towards the need for some type of "HUD" to determine
orientation. We are adding complexity and bandwidth with this idea. I
think it may have to be said up from on your VRW entry point whether or
not the world is a single horizon, fixed path progression or it is a
"fly-through" world and require specific browser capabilities in order to
navigate it.
