I don't require official support, that's why I'm posting here instead of there. I'm asking whether something is technically possible, not whether it's officially supported.
OpenVPN is most commonly run as a daemon, but it's not essential to do so. Since I only need it to serve myself I was planning to run it non-persistently: fire it up with an SSH account when I need it, and kill the process before I log out.
That's good. My question concerns whether it's possible to "roll my own" without buying Strictly Business service.
