- Description: This is the first published video for ejabberd Advanced Erlang Workshop.
- Author: Mickaël Rémond

In this video, I talk about the history of XMPP protocol extensions for group messaging and detail each approach for message broadcasting, from multicast to pubsub.

I also explain how to overcome the limitations of Multi-User Chat protocol to build mobile Whatsapp-like group chat services with ejabberd.
