ID of player that interacted with a physbone or contact receivers

[hauveli]

What's the idea? I want to be able to see which player interacted with my avatar and using OSC, control events sent back to my avatar based on who interacted with it. This could be useful for example to get a timeline of high-fives over a lifetime or as an (dis)allow list for certain interactions.

Is there another way? None I have found.
