Super. Would be interesting to see how good it scales. 200 people in a town-hall meeting will be an interesting engineering challenge I would think.

Having the meeting leader do it 200 times to pass around a shared key generated on the client would be e2e and have minimal if any performance impact. There is probably a cleverer way to do it that I'm not aware of as well. Edit: One issue is the client can run out of entropy but I think that would only happen on modern operating systems if you had hundreds of thousands of clients to negotiate with.
