[FOSDEM] GSM BTS at Fosdem 2011?

Hi all, are there any plans to establish a GSM network next year? If yes, do we need to bring our own SIM cards? Is there anything I should look for when scavenging them? Would someone who works at a telco or similar be able to grab a few SIM cards (scrubbed clean of personal data, obviously)? Would it even help to have a common pool of assorted SIM cards to hand out to people? Personally, I think it would be awesome if things worked out this time :) Richard
