It just works.  Its a pretty low volume site and restricted to certain
networks only. If it were internet facing, I would probably put some
sort of port knocking in front of it as these keys tend not to be the
fastest and bots brute forcing might DoS it. I hadnt done any heavy load
testing. It easily survived my worst case load tests so I didnt bother
going beyond that to see at what point it would break down compared to
storing the private key in a file.
