I like this idea, although you should be able to lock an ender chest so that it disappears off this "e-chest radar" because I know some people don't like others randomly running into their town for an e-chest.

thats such a petty thing to do lol

Even more if landmines are added so that I can just put them around the chest and watch the randoms get blasted to bits after wanting to grab their precious hamburgers from their ender chest.
