So if you get into trouble with it, don't be too surprised. In fact, its use at all in the edge of the network he believes is problematic. There is too little aggregation and too much variability of traffic in a home environment for he or Kathie Nichols to have any belief in sane behaviour in RED 93 given RED's problems. Ergo our interests in SFB and RED Light and eBDP (which Van pointed us at in the first place). - Jim
