Yeah, and Dropbox is just rsync and scp :)

If that's all that was necessary then I feel like a lot of these SaaS tools wouldn't be as popular. I suspect a lot of Tailscale's success is because wireguard is not easy nor does it solve the full problem space (i.e. discovery). With `tailscale serve` I can get a private HTTPS endpoint to my local machine in almost no time.
