I'm very interested in this! Can you say how this compares to something like https://jamkazam.com? One of my issues with JK is that it seems to require all participants to be members, and to pay for relatively pricy memberships to partcipate. I'm sympathetic that nothing is free and I'm willing to pay for a good service, but I'd love to have a model where one person could pay for a session that others could join (with video) for free.

That said, I'm not sure if you plan to start charging.
