Excellent choice.

May I inject a piece of historical data; some of the region/scene/innerscene confusion pertains to us trying to separate the 'scene' from the 'region' way back then.
 
Roughly,
 
The 'scene' would be the 'scenegraph' and deal with controlling the scenegraph model.
 
The 'region' would be the 'endpoint' and deal with communications.
 
Darren started a babysteps refactoring voyage towards moving stuff from 'old Scene' to 'InnerScene', which was supposed to become 'new SceneGraph' and then 'old Scene' would just keep the 'Comms' bits and become the 'new Region Endpoint'.
 
To make matters worse, we also have the RegionInfo, which is the (communicated) data about the 'Region Endpoint' - which seems to cause confusion and hesistance.
 
Alas, this divide has only come half-ways, but when working with communications, we should continue the strife.
 
(So, yes, in theory, endpoints and scenegraphs were supposed to be a many-to-1, not an 1-to-1 - so that a scene, for example, could be 512x512m over four endpoints - making more efficient use of each endpoint thru internal routing.)

Yay for having the comms pluggable, with a base-case Comms Stub. That stub could probably take over some of the standalone/grid mode grittiness. (By, for example, supplying a never-authenticating user service)
