Ack, just realized my shells have been sitting around since '06. This is just a heads-up that they've not been abandoned.
I've found my old notes on what I had plans for, and will be expanding those shortly. I'm leveraging the OpenSim project to do some modeling of complex items, since there are ways to import objects there into Blender via LibSL.
Some items (like the 'bollard and barrier farms' I've mentioned in the past) are simple enough to place directly for now.
