Is there a working example of Node.js software for a Kurento "compisite" (MCU) video conference? 

I have tried this software with a few difference web browsers and a couple of different (recent) versions of Kuento (including 6.16), but it doesn't seem to work.

Does anyone know of a working example of Node.js software for a Kurento "compisite" (MCU protocol) video conference?
