I'm not sure if this is possible yet, but I'd like to see a way for a chest to send out a redstone signal when its inventory becomes full. I do a lot of work making automated factories on my server using plugins like Minecart Mania and PistonChest, and to make sure things don't clog up currently I have to have relief carts roll out on a timer to either move the items elsewhere or toss them out. I like making things as movement-efficient as possible since MM is a pretty big CPU monster when you use it to make giant storage banks, so only sending a cart when it is REALLY needed would be awesome. Perhaps attach a lever to the side of a chest like how Lockette attaches the sign, and make it turn on if the chest it is attached to becomes full?
