Hi Mikael,

	[SM] ... if end-user devices have such capabilities, the big ISPs that in all likelihood are the biggest buyers of such devices, should have little issues adding that to their requirements list for their purchases and making sure devices are configured properly, without driving up the costs unduly, no?. 
	The fact that that has not happened is in itself a rather clear indication that ISPs are really not that interested in tackling latency under load (and why should they, often unhappy users will switch to a higher/more profitable speed tier in a well-intended but not very effective attempt at improving a link's usefulness).
	Now, for end-users that is a different issue, and there are quite some, often on-line gamers interested in reducing their internet access link's latency, that are actually willing to buy and configure boutique devices, like the NetDUMA, or more down to earth and less hyped (but IMHO even more capable) evenroute's iqrouter. Incidentally, both are basically software distributions for relative standard existing router's from other manufacturers, and yet people are paying a premium to get those better behaving router OS, as latency under load performance of stock router OSes often is not "cutting it"...
	
	I note that L4S never reached out to those end-users actually caring for low latency... instead they are trying to convince the ISP market, without a narrative how this is going to imprive an ISP's bottom-line (the you need to do this to not fall behind the competition, is not a positive selling point IMHO).

Best Regards
