As of 12 months ago, I inevitably had problems with more than 3-4 people in a session. But that was mainly when we'd try to rotate presenters. Got used to restarting the call in order to pass the baton. Even without rotating however, there would often be connectivity issues where someone had to drop off and reconnect. That slowed us down with small groups, so if you had to pause anytime one of 50 people had connectivity issues I'd guess it would be unusable unless they fix the connectivity issues. Have you tried youtube for live streaming? Never tried a private stream, but they certainly know how to scale video.
