[Opensim-dev] The essence of "grid"

[Diva Canto]

I think you may be thinking of OpenSim's equivalent to OGP's
"agent domain" -- that's different, and yes, that is our User Server.

"Trust domain", in the context of this discussion, is what Melanie and I 
said over a few emails: a collection of simulators that trust each other 
and that are all under one single authority. They may be associated with 
User services or not -- they may simply be simulators without associated 
user accounts. I think OGP has a name for it too, "region domain" perhaps?
