The first two, yes. I did it myself, back in NZ in the 80s.  You soon
realize that you need to change *both* ends of the TCP;
which isn't always feasible.

I'm less worried over changing keepalives times/rates. Those are
already sysctl'able, , but as you say, we'd need max and min for both
rate and drop-point, changeable only by root, beforehand. Plus a few
more bytes in every tcb; which some users may care about.
