Generally speaking, the packets are being routed via a router/switch, so the timing of packets being sent by the server is in fact masked by the behaviour of the router/switch. It is the router/switch that is feeding the packets to the Touch, not the server... If anything, it will be the behaviour of the router/switch that determines actual packet arrival timings - won't it?
