Mono, if you are talking seriously about making a decent cheat protection for jj2 then I suggest you take a look at how the CSHP (client side hack protection) from UT99 works and then make something that works in a similar way. You can never get as much information from your own server by observing memory/packets as you can from doing the same thing on a client's PC. CSHP really runs a script on the client side and checks for any hacks that might be messing up with the game. This way you'd know for sure if someone is warping (eliminates the false positives that lag can cause). You could also search the processes to find if any match those of jj2 cheating tools, etc. The choices are endless. This approach should be more efficient, but also more difficult to create and manage.
