This demo connects to an ncat chat server.
It allows “users” in two iframes, and any other users connecting to the server, to chat with each other.
$ sudo apt-get install ncat
$ ncat -l 4004 --chat
Open chat.html using a Chromium browser on the same machine as the ncat server.
Use --restricted-api-origins=https://ewilligers.github.io/ when launching Chromium.
