Finger/Hand tracking input for OSC

[InsaneGrox]

What's the idea?
Allow OSC to control hand positions and finger rotations, partially to give PC players a way of utilizing hand tracking if they have the hardware IE: Ultraleap/Leapmotion/Pimax hand trackers, Varjo Built-In handtracking, Quest hand tracking on PC through custom ALVR/ALXR builds, Proper skeletal input, Non-index finger tracking controllers such as etee, VR gloves that support splay, ect.

Is there another way?
Native Ultraleap SDK implementation, though this would limit hand tracking to only be usable for trackers from that vendor, which isn't remotely hardware agnostic, Same goes for proper skeletal input, the only hardware agnostic method aside from OSC I can think of is OpenXR's hand tracking, though that would require a switch to OpenXR, and would leave out desktop users who have hand tracking sensors.

Additional context
There's already hand-tracking on quest, and there's plans to add body tracking to quest via OSC, it doesn't seem like it'd be particularly difficult to add hand tracking to PC via OSC too.

This would be great, additionally adding virtual head/hmd tracking (by setting the head tracker position/rotation) would allow hmd-less (SteamVR w/o an HMD or Desktop/upcoming Mobile mode) FBT

I want this to create a mobile app/desktop program that virtualizes the HMD, hands, and trackers via OSC, creating universal locomotion for all avatars, even on desktop.

EDIT: One could also use this to make VRChat work like a VTuber program (VSeeFace) with the camera and optionally the green screen mask, but with multi-player in-world people, which sounds like a cool idea.
