@sudden pewter came up with this idea, though i refined it and simplified it:
On the new prefab spawner, a toggle called something like "Persist Changes" that will set things so that when a prefab is spawned, and you modify it whilst it's spawned, then you despawn it, and later on re-spawn it, the modifications stay intact
Gear's idea is to use this for things like cars that people can spawn, paint/modify/customize, and then despawn when they leave, that will persist their modifications, so that when they are next spawned again, their car is still painted/modified. This could work even for entire houses and big build projects. It has huge implications for performance problems across servers!
Not sure how hard this would be to implement though...
