yeah. i was thinking that each (terminal) node should have a pointer
to a function that handled it. and/or a pointer to a cookie that the
function could pick over for "hints". of course, that would only be
for sysctls created in kernel space. sysctls created from userland
wouldn't get all the fancy handling.
it's tricky, but it's certainly doable. i have this crazy notion that
ifconfig could be turned into a shell script, but i doubt i'll really
get that far with it... :)
