Re: [mmox] Interop ongoing between OpenSim grids

[Charles Krinke <[e-mail]>]

Ok, well, please stop me if I get too wrapped up in OpenSim stuff that is of
little interest to others as I do not want to appear to be saying "this is
the only way it can be", but you encouraged me, so here is a bit more.

As I understand what is happening, Prof. Crista Lopes is using the CAPS in
the SecondLife viewer as much as practical. Her view of development is based
on the message_template file in LibOMV (formerly libsecondlife). I
understand that both the SL viewer and the Hippo viewer function.

It appears to me that she is keeping an assetServer connection back to the
originating grid to allow inventory to come along and be rezzed (instanced)
in the destination sim. So, this is a matter of re-directing the SecondLife
"circuits" to enable this interop.

Certainly, one can argue that SecondLife and OpenSim are closely related in
at least functionality since OpenSim strives to be compatible with the
SecondLife viewer. But, there are other viewers being used now and I see
this as an ongoing interop effort also. Whether the viewer<->sim definitions
become part of MMOX, I dont know. That will be partly up to this group as it
defines its charter.

Avatars are arriving on OSGrid with names above their heads of the form
"First Last@dottedDecimal:port", which seems as good a way as any to
distinguish some semblance of identity right now to avoid avatar name
collisions.

One last note on OpenSim for now. It turns out that OpenSim does not use the
notion of an AgentDomain or a RegionDomain at all. The OpenSim architecture
consists of five processes that tie a grid together. These five processes,
which can run all on one server on different ports are known as the UGAIM.
UGAIM stands for UserGridAssetInventoryMessaging, and denotes a UserServer,
GridServer, AssetServer, InventoryServer and MessagingServer.
