FOSDEM is the annual Belgian meeting of free software developers. Like in 2005, I would only be able to go there on Saturday (Sunday, we are preparing experiments for Monday, in the lab). A car will thus do the journey from Liege to Bruxelles, on Saturday morning (8.00-8.30) and it will come back in the evening (at around 18.00-19.00, except if we stop in a nice Indian restaurant in Leuven). There are 2 or 3 seats left. If you are interested, please contact me.
