This sounds really interesting, and I wouldn't mind hearing more about it. Our idea was something like Neos or VRchat, but free and open source with the ability for people to host their own servers and link them to the rest of the ecosystem.

Honestly, though, I really don't yet have much experience with this sort of thing which is why it has stayed just an idea, but I'd love to see the idea take off in the hands of those who are more capable.
