[Opensim-dev] Thoughts on adding a generic key-value storage system to OpenSim?

[diva at metaverseink.com]

I think the issue at hand is how to allow plugins (regions modules and 
others) to store additional data in the existing databases. Many times 
the extra data is just a few more fields. Having to setup entire 
databases for those plugins, separate from the existing ones, and 
requiring coordination with the existing ones, seems like an unnecessary 
complexity.

So definitely +1 on jhurliman's proposal.
