If we were to set up a private jitsi server in the colo or cloud, we could set default camera = off, which greatly increased the number of simultaneous viewer connections. And we would also have some preauthorized control users. (One open item - we'd need further research on how to shut down rooms after a meeting is over to prevent trolls taking over.)</div><div dir="auto">(Jitsi support boards suggest that mandating BradyBunch mode also saves bandwidth.

I'm not advocating that, but I may do that temporarily to learn node management. A cloud provider with hibernate discount might be cheaper for a single group!</div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
