Do you think it's possible to make a drawer that automatically destroys incoming items once it is completely full? This is similar to Thaumcraft's Void Jars. It should also act as a lock upgrade. I'd use it to destroy incoming cobble from an Arcane Bore or similar, and destroy rotten flesh from a Furious Zombie farm. Right now I'm managing the overflow using a 1x1 drawer, a lock upgrade, a hopper, a TC item grate, and a lava source block. (The Arcane Bore is dropping items through mirrors into a hopper on a drawer controller, which works wonderfully after I've figured out its search order.)

Oh, never mind, I see you're already working on it!
