[arin-ppml] inevitability of NAT?

Jack,

     The point was the game does _not_ require UPnP nor any port 
forwarding.  However, that is required for voice communication.  I don't 
personally use PSN for voice communications hence I haven't run into 
that problem despite being in NAT category 3 by the PSN definition (I 
have UPnP turned off and no forwarding for my PS3).
