I haven't worked on the project in a while, so I can't comment too much on the current status. But I'm happy to talk about what I learned, the challenges I faced, etc. if you have any questions about those.

The multiplayer aspect is immensely valuable. Having multiple developers walk around the same codebase together, discussing the architecture and the code, is helpful for debugging, onboarding, brainstorming, all the different ways we collaborate as developers. This kind of visualization is not a solo activity, so I can see where Vircadia would come in.
