Having a mini-economy on each faction base would be nifty. Some players may be rich so they can donate credits to it (or maybe it comes with credits, as it\'s still technically owned by the trading guild?) while other players mine stuff and sell it to that block or buy some blocks they need from it. It could also be better for storing items than plexstorage arrays, it would auto sort items, presumably hold a near infinite amount of items. The only catch is that you have to make the buy/sell prices equal or you\'ll end up paying a \"storage fee\". If each faction could only see their specific store-block it could function as a sort of enderchest, or safe storage of items. If the block is destroyed go buy a new one and have access to the items again as they were actually stored in the faction data not the block.
If you could hook a factory, or several to it that would be even better.
