Although there appears to be very little or no cheating experienced on the COD4 servers currently, the reality is that the cheats will soon find a way around Punkbuster, especially as it is largely built of the same engine as COD2. There are some inherent problems with COD4 regarding detection of cheats that will need some consideration before establishing the parameters of the server.

The tools against cheats are Punkbuster and the good old Kill Cam. There are a number of reasons why Kill Cam should not be used in league matches, but a public server surely demands this most basic of countermeasures. However, this will not be without it's problems. The Kill Cam in COD2 did sometimes leave a lot to be desired and often caused more unfounded arguments than it resolved. Most noticeably, the 'real time smoke' issue. However, dispite it's shortcomings, most players would much rather not be without it. However, the same may not necessarily prove to be true with COD4.

There are 2 issues here that may sway the argument. Firstly, shooting through walls. Previously only reserved for the hackers, and now a staple tactic of and half decent player. Secondly, the UAV system. Put bluntly, someone can as good as see you through a wall, and then shoot you through it, all beautifully captured in Kill Cam. How are we supposted to know the difference between this and the cheats? Unfortunately, only time will tell.
