[FOSDEM] requirement to start a devroom

Hi, Dyring fosdem 2017, the amateur-radio society of Belgium has an infobooth to promote amateur-radio at fosdem. (thanks again to the people at fosdem to allow us to do this). I have had an idea in the back of my mind for some time to go a little bit further in this and look at the possiblity to set up a (small) devroom for amateur-radio related topics and open-source/free software and hardware. Some questions (before I start talking to people): Is there still possible to start a new devroom? What are the requirements to set up a devroom at fosdem? How many talks are needed for a devroom? Thanks in advance, Cheerio! Kr. Bonne.
