Right now, we send 96 bits to the server that dictate which clients will 
hear the voice packet...the first bit is client #0, the next is client 
#1, etc. The server only retransmits the voip packet to clients that 
have their bit set (and are willing to accept the data, etc).

This was so you could have arbitrary lists of recipients (all your 
friends, or maybe teammates that aren't in the same room as you, 
etc)...I'm pretty sure cgame keeps a list of who's on your team, so team 
chat would use this, as would "talk to guy in your crosshairs" ... the 
server side could make decisions about retransmission by position if we 
want to add this (so it doesn't send to people out of range of your 
voice in-game, even if you address it to them)...obviously we don't need 
to transmit positions in the voip packets, as the client and server are 
both maintaining this information already.
