Piston Everything is a relatively small coremod that enables vanilla pistons to push tile entities like chests, dispensers, beacons and the like. It adds no new items or blocks. It also features a configurable white or blacklist for controlling what tile entities you can move.
Installation is a simple drop into the mods folder like most other forge mods. Supports MC 1.6 and 1.7.
Here's a video of it in action.
