As an aside, well ran conference WiFi (and public WiFi in general) won't allow attendees to contact each other over the WiFi network - they will only allow traffic from end user devices towards the gateway, and won't allow hairpin routing on that gateway. I wish more public WiFi was well ran, as many of these same network attacks wouldn't have an opportunity to work in the first place.
