#ifdef VOICECHAT
/*
Pivicy issues:
By sending voice chat to a server, you are unsure who might be listening.
Voice can be recorded to an mvd, potentially including voice.
Spectators tracvking you are able to hear team chat of your team.
You're never quite sure if anyone might join the server and your team before you finish saying a sentance.
You run the risk of sounds around you being recorded by quake, including but not limited to: TV channels, loved ones, phones, YouTube videos featuring certain moans.
Default on non-team games is to broadcast.
