If the server could make data that shows who is within 14k of who available to another program, you could then modify the voice chat program to open channels between users that are near each other in game.
You would need IDs from freelancer and the chat program to match to ensure the correct people are put in communication with each other though. I'm not entirely sure what data freelancer stores on this. Perhaps account IDs could be linked to your voice chat ID.
