A lot of stuff is controlled by the server and static because of punkbuster. I've found static, read-only coordinates that can be used to find an editable list of coordinates but they change every time you die. You can mod them to move in the X or Z plane (and teleport around the map), but for some reason I've found Y to be non-editable. That's the only good coordinate to play with! You can control some other client side features like the scout's oracle or the assault's shield to have an infinite amount of both (and you can even toggle heat vision to work without using the heat thing). That's all I've really found so far though. I'm still working on other stuff.
