I do some maintenance for a pretty old LambdaMOO instance that runs enCore, which gives it a (very 90s) web UI, along with a browser-based telnet client. Of course, that telnet client was a Java applet, so I replaced it with a websocket console, and a websocket server that proxies telnet to LambdaMOO. One of the bigger challenges with the web UI is that HTTPS isn't really optional anymore, and the enCore database has a ton of `http:// http://` links. So it requires a reverse proxy in front that can rewrite those, luckily in Nginx it's possible to use a small Javascript program to do it.
