Not the plan. But arguably, we'd need a list of requirements from a
major head-end
vendor or DPI co (like sandvine) to even try to address the ISP side
of the universe.

I long ago ran out of motivation and money to continue working on
bufferbloat. It's fixed enough,
for those that care. It's on enough devices (more every day) now to
give those that succeed some market advantage.

Heaving cake over the transom is the "last" thing. And after 18
versions in the last round, toke's fried, I'm fried, everybody's
fried. I'm very happy it started cracking 40gbits, stumped at the bug
stopping us.

I do long for the day where I could buy a cable modem, dsl device, can
bus, ont, gpon, wireless router, enode-b, etc, etc off the shelf,
clearly  marketed with bufferbloat-related fixes - and ISPs will
supply default gear that worked "right", etc, etc that all did the
right thing... but I figure that's going to take explicit market
demand, regulation, or a miracle - or all three. And a decade. Or

I *am* going to washington DC week after next for the lanman2018
presentation of cake, and perhaps I'll find a way to raise some hell
with the FCC, congress, or the FTC (suggestions wanted), but...
