	Ah, sorry, I fully agree; and if ISPs are interested they should start talking; I just wanted to report the one case where cake seems to be used in an ISP-ish context.

	I had hoped that orangetek could be convinced to do measurements with different number of queues to answer that question, but I guess the current default of 1000 queues is decent for a typical homenet, but will simply become a bit tight with 600 concurrent households (I assume that its the peak usage that would want more queues on the "back-haul", on average 1000 might still be okay, especially with Jonathan's clever set associativity design)
