[Opensim-dev] [Opensim-users] grid operation

[Dahlia Trimble]

Agreed, standalone is quite useful. I use it for development and have
several standalone regions that I use for content creation offline from any
grid. I can also see standalone being used for non multiuser applications
such as single player games or other 3d applications where internet access
does not add any value, where the server can run alongside the client on the
same pc.
