Hmm, what I was thinking of was that everyone seemed to be competing with each other to click random UI elements on the virtual browser as rapidly as possible, I assume because there wasn't a way to speak with one another / coordinate. Or maybe I just missed the chat area?

Yeah we kept the MVP lean and didn't add chat or audio/video calling. Our goal (which we're not meeting) is to keep the Three.js example line count below 200.

We'll probably make a new project which is more of a product and less of a code example in the future.

Looks good so far, looking forward to seeing more :)
