I have this setup on a $5 Vultr instance running Fedora 30, complete with a subdomain, Let's Encrypt and 2FA. I've also got it running as a systemd service running under a limited user account.
I'm only testing with a handful of personal computers right now, but everything just seems to work, and does so quickly. Having secure, easy access to a computer's desktop, files and terminal through a web browser is fantastic! I'm still learning all the features and capabilities, but I'm very impressed with what I have seen so far. Awesome stuff @Ylian!
