I've just built a new thing for forwarding local http applications to an https subdomain.

- ssh app@ssh.my-ns.me with your key (your key is the only identity I ever need)
- pay 1000 sat invoice (once per ssh key, lifetime membership)
- ssh -R80:localhost:5000 app@ssh.my-ns.me to forward the application running on http://localhost:5000 to https://<your four-letter subdomain>.app.my-ns.me
