I know you are working on new worlds and coming up with new strategies for extending the life of existing worlds. The TerrainControl plugin presently creates a Read-Only layer when an existing world is edited that consists of all the places that have been edited from the original. This isn't particularly useful when dealing with a world as well used as those in present use on MassiveCraft. If, in contrast, the faction plugin could produce a Read-Only map that marked all the claimed land, compatible with the Read-Only layer TerrainControl uses for world merging, then it would be possible to update an entire TerrainControl world while keeping existing factions and claims intact.
This would still need to be a rare occurrence, with much advanced notice so people can move their chests on unclaimed land, but might also allow for implementation of some of the other new strategies for extending world life.
