Simple hacks (with proof)

[Obsidian]

well what i did with my source... and again packet encryption is by far the best route... but i just made two seperate clients. One for players and one for admins. The "player" client has all of the admin stuff completely removed, and the "admin" client sends an encrypted "key" at the end of each packet. so in the event that someone tries to spoof my packets on the client version, if that string is not found they're autobanned. It's more work... but i feel it'll be worth it in the long run.

[Edit]
I gave your packet editor/sniffer a throw, and it won't listen to ms based games (or atleast mine) because the address(es) for the client/server are already in use.
