This feature seems to be offering similar functionality to OpenVPN's tls-auth which requires an additional key before a connection is allowed. Another option to get similar functionality would be to use port knocking [1][2] but spiped gives other useful functionality too.

I was intending to mention port knocking in that blog post but didn't find a convenient point to fit it in. Yes, it's definitely an alternative solution to the "let me connect to sshd but not anyone else" problem.
