Thats the point, the DMZ isn't part of the QoS jurisdiction, so to speak. So it's like having two lines at a toll booth. One line is split up into three, for people paying with cash, credit, or EZpass. The other line is just for one person(a VIP), and their is no charge for him to go through, he can speed through as fast as he wants. That may sound perfect, until you consider the other side of the tollbooth. That VIP may be able to zip through the tollbooth as fast as he wants, but he still hits the traffic on the other side as it merges back onto the highway. Does that make sense? Giving priority to the PS3 is not a bad thing, but you have to be careful that you don't just amplify the bottleneck between the router and the ISP.
