-There is only a max of 8 players per map.
-Technically it is not a Server but a hosted game. Because if the player who owns the world logs out or exits minecraft. The world will "sleep".
-Split screen co-op can be up to 4 local split screen. And even online. Splitscreen does not work on 4:3 TVs. (SDTV)

To play Co-op, you need to have TWO account on your xbox (They dont need to be gold). The second player needs a second account logged in. He then can play the MAP the first player has created IF HE HAS A CONTROLLER WITH A SECOND ACCOUNT. The second player need to just press start on the controller.
