There are many notes about latency, how it can/cannot be solved etc. This ignores a basic technique being used by most vid conf vendors that is not music friendly - unpredictable (non contant) network delays happen, and to help counter that, most software speeds up the audio playback occasionally to help clients catch up when audio arrives later than expected. This is a HUGE deal breaker for music lessons as it wreaks havoc on musical timing .. even when the lesson does not require live playing together. Just turning this off would make a big difference to online music lessons I think. The "speed it up to catch up" technique is fine for speech .. which is the dominant usecase.
