TODO: Authoritative State.

• Most state is pertinent only to objects and maintained by objects (within the object host, most likely by the object script itself).
• Some should be maintained on a per-object basis by the object host in order to provide additional services (e.g. mesh URLs to automatically maintain mesh, physics bounding mesh, bounding region, and communicate those to the space automatically).
• And finally, some *must* be maintained by the space because it is critical that it be consistently seen by all participants and because it affects interactions between objects at the lowest level. Examples include object locations and bounding regions.
