A realtime event management platform

Would someone be interested in a platform where each session in the event would be interactive, meaning the audience can interact with the speakers, respond to relevant polls, questions, etc. using a mobile app. And the event organizers will get to post the polls, questions etc in each session and switch between them in realtime.
So, basically I am proposing a full fledged platform where admin, moderator and the audience get involved in any event.
