[Opensim-users] revised terms...

[Diva Canto]

Paul,

Your division of logical vs physical space is right on. But I think this 
is closer to reality, though:

1 Logical Space
1.1 A region is 65,536 sq. meters and infinite Z space, which provides a 
3D space *service*
1.2 A Map (logical grid, matrix) contains one or more regions.
1.3 A collection of *services* glue the regions together. Those services 
are:
      grid service, user service, asset service, inventory service, and 
others.

2 Physical space
The different *services* mentioned above are implemented by *servers*. 
Servers can run one or more of those services.
2.1 In the simplest case, there is only one server running all the 
services. This is known as "standalone".
2.2 In another common configuration, one or more servers run the 3D 
space service (1 or more regions per server) and independent servers run 
the glue services. This common configuration is known as "grid".
