IIRC P2P doesn't scale beyond a few participants because all the streams are going to all participants. Centralized can reduce bandwidth and number of data exchanges

Maybe, I've had 10 in a room w/o much issue - but my team is all on good pipes. It's not a webinar.

I think Skype P2P relied on super nodes which had the best bandwidth and processing
