The XSF will hold its 6th XMPP Summit in Brussels on February 7-9. The first day (Saturday) will be held at FOSDEM 2009, featuring public talks for larger audiences and perhaps a birthday party to celebrate the 10th anniversary of Jabber technologies.
The second two days (Sunday and Monday) will be held at another location (probably a hotel), focusing on technology discussions and hackfests among a smaller group of core contributors. Full details are still being worked out, but I wanted folks to at least know about the dates and location so that you can plan ahead. /psa
