I Had 3 ideas:

First I had see on another game server (the program where called Bukkit) you can put some plugins on a extra folder where called plugins and change the gameplay. Also i want this will available for JJ2.

Second Idea is the command /broadcast, it send message as "Server: "

Third idea is some extra command for get me r. For example : /getmer -nt means "do not teleport me to the base.

EDIT:
Also i want JJ2 support more that 32 players. Max 128 players is OK!
