Recently i was building a prototype castle, the idea was to find a high peak, strip off 5 or 6 layers of dirt and use natural shape of the mountain to dictate castle shape, anyway when i finally built it i used two iron doors side by side as entrance(since castle gates are not implemented yet) and there i noticed a flaw, whichever way i used to open the door, be it button, leaver or preasure plate it would be exposed to the enemy, on my SP it is not that big of a deal as NPCs can't flip the switch so i can safely put leaver outside but on servers, baring some kind of redstone contraption the enemy can just stroll right past your defences, open the gate and get in, you either must have someone inside to open the door for you or else leave yourself exposed, the idea is there would be this special NPC you could tie to the specific leaver, when you do that you get a signal item(flag, pole maybe or something) select it in range of the NPC and activate with right click and he opens and closes the door for you.
