I think there was a thread about this a while ago. It depends on what exactly the system would entail, as to the complexity of it. -if it just appears that you are holding the gun on the left in your HUD, but to other players, it looks like you are holding it in your right, it'd probably be reasonably possible to integrate. -if it outwardly appeared as you are holding the gun on your left, then all the character animations would have to be "mirrored" to suit. This could be a lot of work. Ultimately, I think it would be a great thing to implement, and be a "next step" in the ability to customise our characters. Also, #sinister
