@hansw @torresjrjr I know that emacsconf used BBB for the talks but they were then streamed using gstreamer and a few other tools to a website,.

As mentioned now there is peertube streaming, it makes things much better.

Is there an equivalent to emacsconf, libreplanet but for Mastodon ?

With BBB you just need a link and a passcode (if one is set) same as you do with zoom, only BBB is open source and more private,
