In this case, the guy wants either a direct SSL tunnel or an
encrypted ssh (perhaps port 22 is the only thing he leaves
open on his box at home) tunnel.... so in this case there
was a need for the extra process.

Doing everything with the kernel is not a great idea anyway...
especially if the work can be done in userland.

iptables was the word you were searching for.
