Hi Matt, I'd kind of think that an instancing mechanism would need to come first. Maybe just an instancing system alone would solve some of the current issues like with file size.

If it's causing a lot of difficulty right now you might benefit from using Rhino to manage the different configurations.

That doesn't mean that I don't think that MoI won't have some kind of configuration state in the future, just that it's not really on the radar right now as a prominent high priority item.
