I had this crazy idea last night about restarting the server.
What if you built two rooms in spawn fortress, each room has an iron door with pressure plates to open it, and a button (not reachable from the doorway). The buttons are connected in a standard "and" fashion and the output is connected to a command block which restarts the server (if that is even possible to do with command blocks, I don't know). Then it is made sure that the entire area is put under total protection so it's impossible to edit the blocks.
The idea, then, is that if the server starts acting up, but before it crashes, two people can in agreement push the buttons at the same time to restart the server. The setup makes sure not any one person can do this, it has to be two.
