I for one would love direct chat only once radios are implemented (much like ACRE). For all of you who haven't experienced it, it's just amazing how much it adds to the immersion. I don't know if there is a way to prevent players from using TS or ventrilo, but I would really appreciate it. Could we check if there is e.g. a teamspeak.exe running? Or would this be too easy to bypass, are there legal difficulties?
