Fredashay's Redstone Device Tamper Protect

This plugin protects players' redstone devices from tampering.

And that's all this plugin does.
This plugin does not prevent anyone from destroying any redstone devices -- use a grief protection plugin for that.
It also does not prevent players from pressing buttons or turning switches or activating pressure plates -- it only prevents players from right-clicking on repeaters and other devices to break players' redstone contraptions.

Players can allow other players to access their devices.

In-game commands are as follows:

/DEVICE HELP - Will display a help message outlining the following commands to the player who issued this command.
/DEVICE ALLOW [PLAYER] - The player who issued this command will allow the named player to alter his device settings. This permission will last until the owner of the device leaves the game.
/DEVICE LIST - The player will get a list of all players he has allowed to alter his device settings.
/DEVICE SHOW - The player will be shown all his nearby devices.
/DEVICE REVOKE [PLAYER] - Will remove permission from the named player to access the owner player's device settings.
/DEVICE OP SHOW [PLAYER] - Will show all nearby devices owned by the named player.

To install this plugin, copy the plugin JAR file to your server's plugins folder.
