An experiment well worth doing, and probably a preferable option for people weary of listening politely to 'authorities' or 'guests' or 'lecturers' one-at-a-time... which can be extremely low-bandwidth.

Certainly at conventions with 'presentations' many people sit near each other to discuss what's being said (or talk past the parts not relevant to them) in real-time. Orchestras still have conductors (strictly interpreting fixed works) but I think most people would rather be in a band (for the creative interactivity) and rather listen to a band.
