For those using Debian/Ubuntu (and anybody else is welcome of course), there is a mini-DebConf in Paris this weekend: http://fr2012.mini.debconf.org/ There is a presentation at 16:00 about Debian's role in establishing an alternative to Skype, this will look at some of the packages available on the upcoming Debian 7 (wheezy), and strategic ways of deploying them to build a genuinely free and open cloud for real-time communications. There is no registration fee - all welcome
