thats not the packet shaper, thats the throttle
packet shaping rules that ive seen for p2p ussually manipulate the connection ie block peers connecting to you if you have x connections already or if your speed is x, so you can have one peer giving 40k and 5 others giving 1k each. thats why they use the throttle in conjunction with the packet shaper, which should basically be 2 sets of rules thr traffic passes through on its way through the intelligent firewall
but with wbs' system who knows how they throttle
