To be fair I am right there with you, I was just pointing out how nifty they can be conceptually. How is this for a real world example, that wifi interface that you configured via the GUI and clicked "do not share with other users" exists exclusively in your users namespace, ifconfig only shows it to you, other users simply don't see it and have no access to its routes? Is that a saner example of how this implementation can be used?
