Installing etherpad or ethercalc in the same box with KALite

I was thinking of installing both etherpad or ethercalc along with KALite in the same box and was
wondering if someone else have done that before and can share some ideas.

Try installing ka-lite-raspberry-pi, the Debian package. This will configure Nginx to proxy KA Lite. You could then go on to configure Nginx for Etherpad in a similar way.
