Handtracking possible with a WebXR build?

Hello all,

Is it possible to make a webgl/webxr/webvr build for the Quest that utilizes the Hand Tracking over the web? I realize it works fine for normal controller tracking and interactions, however I am curious if the hand tracking can be used online? I feel like the cameras won't stream the input over the web but I am wondering what you guys think on the subject? 

Thanks!
