I’m collecting different setups here. Other efforts are underway to organize a virtual conference. The setups listed below aim for smaller audiences with hopefully lower effort in setting things up.
I don’t discuss the other stuff needed for organizing a conference, like the social aspects (“hallway track”, “moderation”, “timekeeping”) or how people can forward questions from the chat to the speaker. The logistic aspects are mostly that outside of the “producer”, ideally nobody needs to install software beyond Chromium or another browser compatible enough with Jitsi to do video streaming.
