   8 // Proxy object manager
   9 //
  10 // In a networked environment, each machine "owns" some of the objects in
  11 // the game. All of the other machines maintain "proxies" for those objects:
  12 // simplified versions of the objects, which have the same archetype and
  13 // position information, but which aren't as fully simulated as the real
  14 // object.
  15 //
  16 // The proxy manager keeps track of hash tables that map between the real
  17 // host objIDs to the local proxies. Conceptually, it is closely related
  18 // to objsys.
