Oculus Quest Local Multiplayer News

In the recent weeks I found 3 Teams who already made a similar local multiplayer game with Quest as Oculus promoted the Quest on the Connect event with Dead'n'Buried. The Canadian Phenomena made a game named Versus. It's a "lasertag" shooter game for 1vs1 up to 4vs4 players or maybe more. They using a PC as a server with no internet connection, and the quests connected to this via wifi. There is a team in Vietnam, I have no info about them. And I found an article about a company from New-Zeland. Find the links below...

So there is some light in the mystique of Quest based local multiplayer development. Searching for this knowledge and asking people about this is my daily routine now.
Is there anyone who found any usable documentation, technical blueprint to set up this thing in unity? Do you know someone, who know something? Do you know other teams or companies who break this wall already? Please share the info. Hi5 fam!

I would certainly like some insight into this as well.

Edit:

Here are a couple of options.

Antilatency Tracking System

Azure Spacial Markers

 

This it the best I could find, and looks like it only works on Unreal Engine
