This example shows how to use dotNet to communicate with game servers using RCON.
RCON is used in alot of Quake-like games, like Counter-Strike, Wolfenstein: Enemy Territory, and Call of Duty.
I've tested this with W:ET, so if you have any problems running this on other RCON-compatible servers, please tell me
(also, the example is half-commented, just post, I'll explain)
