I used to run something like that at some point. It basically was a Dropbox account for syncing to a Pi, a python script that monitored changes in a folder hosted on that Pi and would recompile a harp.js website that would then be gitted to Heroku. I still have some sticky fingers from all that glue but it was good time.
