I can tell you there are hundred of different *valid* setups, especially in server farms, when you want some control of network trafic, now machines have Gb or 10Gb links... Really, there is no "one big thing that solves all problems, automatically" You are doing a great job, but now we need to split all your findings into small units and eventually fix problems. Do not expect everything to work, since few people are interested to make the necessary kernel changes in their free time. BTW, latest stuff uses DRR & HFSC ;) Patrick sample script is here : http://people.netfilter.org/kaber/shaping
