[FOSDEM] Running a GSM BTS at fosdem ?

Hi, Back in november/december, I made a request to the IBPT for a special temporary GSM licence. I was originally planning to use it in a talk on GSM but my proposal wasn't selected. Since the authorization has now been granted (and paid for), it'd be a waste not to use it The idea would just to have a single BTS running a small demo network with just A4 sheets around pointing to a website for more infos, no stand or anything. Can this be arranged on short notice ? Who should I talk to for details ? Cheers, Sylvain
