By @[Crysis], don't you think it would be amazing to hear 8 year olds cry after they get PK'd??

I truly hope they don't put voice chat on RS for the sake of world 2 trading. And I highly doubt there would be enough bandwidth.
Put into perspective: The average voice quality on a Teamspeak 3 channel is between 5-7kbps (When someone talks, 5-7kbps is sent to the server. In turn that needs to be then sent on to all the users in the channel at 5-7kbps/user). Multiply that by 2000 (Full RS server), and thats 10Mbps (1.2MB/s) half-duplex (if my maths/logic is right).
Also, how would they calculate the distance in which the voice can be heard? Because I don't want to be in lumby and hear people in G.E.
