!XMPP only does one-to-one video chat, at least in the clients we tested. There was a discussion about what video chat software to use on the !Ubuntuca mailing list: https://lists.ubuntu.com/archives/ubuntu-ca/2014-January/010222.html And we had some practice sessions on IRC: http://irclogs.ubuntu.com/2014/01/06/%23ubuntu-ca.html and http://irclogs.ubuntu.com/2014/01/12/%23ubuntu-ca.html and http://irclogs.ubuntu.com/2014/01/23/%23ubuntu-ca.html
