Rkynick did something similar to this, but it was "radio chat". The farther away they were, the more "static" occured in the message.
Doesn't seem to fit in.People may need to talk from a distance to at least talk.This would piss a lot of chatty chatter that chat for the chat of it.(Oh, too much 'chats.')
So, like...Right next to you: "Oh, I didn't see you there."Thirty feet away: "O.. I d..n'. s.e .ou ..ere."
That doesn't sound very good:"Hey, I found a Fire Truck you guys!""Hey, . ......... . F... ..uck you guys!"
