The idea being that you can do (for example):

# echo 1 > /kern/sysctl/net/inet/ip/ip_forwarding

to enable IP forwarding, as well as the usual file ops. ?
I don't want to say "no", but I'd want a fairly large consensus on that
sort of thing before doing so.  I see that sort of thing as a Linuxism,
which may be good or bad.  I guess this _isn't_ procfs (unlike Linux :).
