[Opensim-users] How to move the gatekeeper service to it's own port?

[Diva Canto]

In my dreams, I get to have one week to document this whole 
configuration mechanism... In reality, I don't have that time, so let me 
briefly explain the main idea.

We have split the resources that OpenSim uses into a bunch of little 
services that, in turn, access the persistent storage backend. Because 
people have all kinds of scalability requirements for their virtual 
worlds, these little services can either run in the same process as the 
simulator itself (the smallest possible configuration, aka standalone) 
or they can run in other processes on the same machine or even on other 
machines. They're all splittable and "aggregable" with configuration 
switches.

Some services "talk" to others. For example, the Login service doesn't 
even have any storage associated with it, it's simply an aggregation of 
other services; the UserAccount service needs to access Auth, Presence, 
Grid and Inventory in order to create new accounts; the Gatekeeper and 
the UserAgents talk to each other; etc.

So in the configuration sections we need to specify how a given service 
accesses the other services. If they are in the same process, we simply 
instantiate the service objects directly, so things in 
OpenSim.Services.<some service>.dll; if, however, the services a 
specific service needs run on a separate process/machine, then we need 
to specify a network connector for them, so stuff in 
OpenSim.Connectors.dll, and then we need to provide an ServerURI that 
each of those connectors will use to find the right process.

I know this is not the ultimate reference guide, but I hope this helps 
shed some light for the possibilities...
