	Is that really true? given enough concurrent flows, critical flows might be delayed purely be the round robin scheduling of equally "worthy" packets in fq_codel, so some residual priory system might still make sense...

	mmmh, currently in Germany residential fiber tops out at 200Mbit/s, cable at 150, and VDSL tops out at 50Mbit/s. Next year cable companies promised 200Mbit/s and the biggest VDSL provider promised100Mbit/sec (G.993.5 Vectoring). So, the wndr3[7,8]00 are getting a bit long in the tooth.
	What would be a reasonable replacement, anybody any good ideas?
	@Dave: for the one tier shaper, maybe using TBF instead of HTB will allow higher shaping rates? (I happily admit , I have no clue which part of HTB is the expensive one, the token bucket filter or the hierarchy.)

	Being more cautious, not to say cowardly, I would opt for hiding the non-default features :) Kidding aside, what should be the default?
