Editing OpenSimulator Internals/Simulator Services (section)

=== Notes ===

* The local connector maintains a <code>Dictionary&lt;UUID, Scene&gt;</code> keyed
  by region UUID. <code>GetScene()</code> has a fallback that returns the first
  available scene if the requested UUID is not found -- this masks bugs and is
  noted as a known issue in the source.
* <code>QueryAccess</code> enforces a version check: if the requesting simulator
  is running protocol version below 0.3 and the destination is a varregion
  (non-256x256), the request is denied. Older viewers crash on varregions.
* <code>RemoteSimulationConnectorModule</code> wraps a
  <code>LocalSimulationConnectorModule</code> instance as its local backend.
  All calls try local first, then fall through to HTTP only if the destination
  is confirmed not-local via <code>IsLocalRegion()</code>.
* <code>source</code> in <code>CreateAgent</code> may be null if the user logged
  in directly or arrived from an older simulator that does not send it.
