I was a bit worried about that too, but than i thought it will more than likely get option's to enable/disable server side along side with quality and how many ppl can talk at 1 time maybe, how far dose sound travel so on. I'm sure it will be sometime before this would be good enough to see the light of day even if they liked it enough to try to start building a prototype. Sadly i can also see how enabling a system like this on a pz server would maybe take a bit more out of the server, I helped build a server on a 2.1GHz HP laptop with 3GB ram and 32bit OS on a wifi net, and it held 6-8 ppl with almost no lag at all, all tho ping did jump alittle high for 1 person when like 3 ppl was running around exploring at same time from what i understand Side note server set only to use 1GB of ram. So my best guess would be if they had the VoIP system too instead of being able to hold 6-8 ppl with almost no lag it would be 2-4. Also PZ team GG on having a well balanced server, i was super impressed that with how good that craptop could run the server
