below is some additional info from the organizers, still not too much clarity. We've decided to go and check it out but not exhibit/speak.
--this is the first event in Canada although identical events are organized in USA, UK and various countries throughout Central and Latin America.
The events are boutique niche events, very focused with no tyre kickers. Average attendance in UK is aroud the 60 – 80 peaking at 150, in USA have been similar and in Latin America much higher around the 120 – 150 mark peaking at 200--
Also in reply to your questions, John: 900USD includes the table top setup and a speaking opportunity (20 min presentation). the attendee information would have become available if we exhibited i guess, this was not confirmed.
