That's actually what I'm doing for my day job and part of why I originally built this. I built the 2D map for Calla because I was still in the middle of converting all my VR work from Unity to WebXR. But pretty soon, VR will be possible.

Technically, Calla is just the library for driving Jitsi and adding spatialization. You can do whatever graphics you want with it. The graphical elements and the interactions are all up to you to build, separately from the teleconferencing.

You mean like in

Have we not been living through the same pandemic? Nobody in the US has a reliable internet connection, services are controlled by third parties and randomly black out, infrastructure is overloaded, meetings are insecure, people step away from their keyboards and are unreachable, there are screaming kids in the background, etc.? I would happily board a plane for work travel right now, this is like living in a parody of my previous job.
