Automatic updates: The server will update automatically when a new version is available (optional). Scripting friendly: The server can be controlled through a standard TCP/IP connection, making scripts very easy to develop (e.g. creating new accounts through php). Remote administration: The server and graphical user interface is separated which easily enables remote maintenance of the server.
