I was wondering if you could add support for currencies in an upcoming version? It would be a cost/block configurable in the configuration.
For example, it could cost 1<currency> ($, gold, coin, or whatever is used on the server) per block to protect. As another example, if the cost in the server is 0.5$/block, a 4x6 area would cost 12$ to protect.

The numbers would always be rounded up to evade exploit when selling/buying regions (wich would also be part of the currency support).
