I haven't thought this through really at all, so just putting a possible idea out there to discuss/be shot down because of stupidity etc. Without introducing something like ACRE, an easy alpha-friendly workaround (while something substantial is developed) could include some kind of rare item drop that gives a password to a TeamSpeak server/channel associated with the server you're currently on (essentially finding a radio). Not sure what kind of load TS servers are capable of, so given the huge popularity of Day Z recently (with AusArma putting up new/bigger servers seemingly all the time) it may not be feasible at all. First obvious obstacle would be everybody telling everybody the password over side. Not sure how you'd deal with that. Maybe it would only work if direct chat is fixed, then side/global/command/everything else disabled. Obviously you could then magically 'duplicate' the radio by giving it to your friends... Also, what's to stop everybody just jumping on a TS server of their choosing beforehand... I'm not sure. But this might give an incentive for player communication with strangers on the same server which you would otherwise not bother to do. You could set up sub-channels to simulate radio channels, and switch between them etc. Anyway, silly idea and I'm rambling. But could be expanded on if anything is salvagable!
