Lynckia compared to meet.jit.si Videobridge

Jitsi Meet is also an scalable open source web conferencing system based on
WebRTC and Jitsi Videobridge (see
https://jitsi.org/Projects/JitsiVideobridge).

One of the differences to Lynckia is that Jitsi Meet uses a multi stream
which sends multiple video streams within the same peer connection. Lynckia
uses multiple peer connections.

That’s also the reason it is not working in Firefox for now.

Where do you see the pros and cons compared to Lynckia regarding their
architecture and scalability?
