It could be generalised such that you could use a sequence of knocks on
different ports mapped to keystrokes.  A sort of "port password" sent
unencrypted across the network.

I don't mean to say that it has no benefit, but it's not really any better
than a password, it's just an extra one that's currently quite obscure.
