Is the primary motivation here to allow unprivileged guests with
networking without providing unprivileged access to raw networking or
just to make networking Just Work?
We've explored various things in the past like using a fscap based
helper to open tap devices which can help with the Just Works parts.
Usermode TCP/IP can be quite cumbersome for users as things like ping
and ip6 won't work properly.
