Just in time project! Do you know if it is possible to just switch a Thunderbolt dock? I mean: you have, fir example, four computers all supporting Thunderbolt and you just switch a USB-C between those comouters?

I have not tried because I am concern with affecting the hardware. Based on your inspiration I just found Thunderbolt KVMs such as [1] and [2].

Wouldn't count on that. Thunderbolt is USB-C just visually. It's probably better to think of it as PCIe that coincidentally has the shape of a USB connector.

I would suspect problems, all of my thunderbolt docks seem to have a 'boot-up' period when powered-on and switched to.

It would probably work if you were okay with the delays.

oooh, not sure. I suspect Thunderbolt has very specific requirements, and switches would be consequently expensive.
