the packet shaping effect things like bit torrent packets usenet packets ect... (unless using ssh) and only hits those with high usage at these times.
Its not effecting everyone in that area..

I have used traffic shaping on private networks and your idea that uneffected packets get delayed i dont understand as i have niver seen this. More as it only effects the packets coming for X modem with X header on packet.
