Sakki's Client Essentials (SCE) has been created out of need to protect the player's client from modification. This purpose of this is to prevent users from applying non-wanted hacks, mods or other such means of bypassing the system that the Server Administrator has put in place. The primary feature of SCE is to secure the client in such a way that players are forced to use a client based on what the server has "approved" of. These clients are maintained, configured, and set by the Server Admin. If a player attempts modifying the client in any way, the server will react based on what the Server Admin has chosen.
This is a Client MOD which compliments the Server Plugin found here : http://dev.bukkit.org/bukkit-plugins/sce/
