Ready made spawn for servers

this redstone device is made to replicate plugins such as essentials. this map is by no means finished, this is an early stage in development and is very basic. this is for the latest snapshot so if you go on normal 1.3.2 it WILL NOT WORK. thank you for your time in reading this and please tell me how to improve.
P.S. i am working on some walls right now so you dont have to worry about people coming in survival and wrecking spawn :D.
also make sure you have command blocks set to true in the server properties. other than that... ENJOY :D
P.P.S. the building area will be made small just so you guys know :D
