On a related note, I came across this USB-C KVM on pre-order the other day. It ostensibly supports Tailscale, which would be really useful.
Was posting "Now make it join Tailnets." to the comments then saw your remark.
TY for link.
I have the predecessor at home, it's solid and the tailscale support is great!
I own 3 of these for my homelab. They work really well w/ Tailscale! They sell some PCIE ones, too.
