It would be awesome if we could define a block that when placed will let us define a cuboid that when allowed people enter the field it activated linked blocks to power or un-power them depending on the setup.

Setup could be sneak left click the precious stone to open field and define trigger volume as a normal cuboid.. once field is closed the next step is to click the blocks you want to power. Clicking a block more than once will toggle the active state between on and off. Right clicking the block will change the delay before triggering. Shift left click in the trigger field to close. powered blocks should not need to be in trigger field..

An example of this would be a simple door. it opens when allowed players approach the door and closes after they pass through the door. the block could be under where the door is placed and its block id can be configurable through the config.yml. Imagine the complex piston devices that you could create with out the constraints of placing redstone. Powering the piston directly rather than a block next to it would be awesome thus making piston doors usable in tighter spaces.

I know there are other plugins that do something similar to this but they do not have zone triggers and they use other blocks to relay signal rather than powering the block directly.
