It took me a few reads to get why this mattered... this is for my wife's

okay, thanks.

Good.  I'm not entirely sure that I care actually, given that I can
create vlans... assuming I can get Gigabit to somehow work directly with
my Cisco switch.

I agree with it.

well, my firewall rules/policy are somewhat more complex than just
lan/guest.   I will have:
        trusted (very few incomng ports open, only from known places)
        service (many incoming ports open, few outgoing open)
        wireless ("sw", gets access to printer)
        guest    ("gw", outgoing only, probably NATed)

Not yet.

My laptop now spends most days at home in it's docking station, as
"desktop", and I have transitioned to a desktop computer at CREDIL, but
I ssh to home to run xemacs+mhe... and *I* sure notice bufferbloat.
(I also run sshfs in both directions at the same time, plus have a 7
year old that would spend all day on youtube if we let him...)
This is despite my ISP having put some QoS at their end....  I have some
very clear smokeping pictures. I hope that codel at my end will help.
