Right now the only thing we can define for team radios is if everyone has it and at what range the radio is enabled.
I am proposing the ability to disable talking or hearing the radio (independently, so someone could hear but not talk, someone could talk but not hear) via roles could open up a lot more possibilities.
Another thing that could be really useful is the ability to remove the team requirement altogether. Add a radio channel option to the roles as well so we can have defined radios that may be team based by default, but could be redefined to allow for double agent type games or for non game rooms that need multiple lines of communication (like a theater for instance)
