This is a Messenger Plus! script I made back in June that publishes your status to a web-accessible page. It’s unfinished and I’m providing it as is for now, since I figured you lot might like to try it. The backend is written in Flask/Python.
Server: https://repl.it/@dotcomboom/status (if you get errors updating the status, make sure the site is up here. The home page goes to my status.)
Plus! script: Web Status.zip (16.0 KB, .plsc in a zip file)
A little editing of the script is necessary for configuration.
