If so, the first one is a true/false node for "remote" devices. If set to "true," (Or "false," whichever you want), it would allow players who didn't set the remote item to disarm it. For example, player1 places a remote device called "Nuke" that takes 60 seconds to detonate. Player2 kills player1 and, without player1's interference, can now disarm the "Nuke," even though he isn't the player who placed it.

The second feature would be a 5th device type that functions the same as TNT, (Placing a block on the ground, it can be detonated by activating it with redstone), except that the player can configure the explosion radius, the damage, etc, but most importantly, its appearance to be anything they want. For example, a player could create a [5th explosive item type] item that has the same stats as TNT, but is disguised as a grass block, or a stone block, or any type of block they wanted. They could make it half as powerful as TNT, they could make it twice as powerful; they could configure it however they want.

A nice add-on for the second feature could be a true/false node for the 5th device to activate if a player gets too close, or another node: the ability to set a "remote control" item to detonate it at will, regardless of enemy players' proximity to it.

Most importantly, I'd need this update to work on a minecraft 1.6.4 server.
