Probably gets pretty costly if you’re running a lot of data through it. Now if you could implement a Tailscale DERP server in a lambda that would be pretty amazing: https://tailscale.com/kb/1232/derp-servers

I did toy around with Tailscale initially trying to get it to spin up as an exit node but wasn't able to get that functional. I did manage to get Tailscale Funnel to work as the tunnel mechanism to Lambda, but unfortunately the performance was really poor.
