So, on this topic, I'm happy to elaborate.  I did most of my initial
research on the topic at https://lartc.org/.  There's a lot more to be
explored beyond the policy routing stuff there.

Future plans on this include possibly ditching Comcast.  But at the
same time, they're sending me flyers about multi-gigabit (symmetric?)
fiber optic installs coming to my neighborhood in the near future.  So
keeping my options open for now...
