Would it be possible to add a system of land by clan, with a power system, a clan starts with power and for each member power is added. A member loses power if he dies (min -10) and wins with time or if he kills someone (10 max). A clan could claim an enemy clan if its power is negative. Each clan would need 10 power to make a claim, once claim it loses the 10. If it loses a claim it gains 10 power.
A claim would be worth a chunk.
This system is similar to the faction plugin on bukkit.
It is really useful for pvp servers.
