A nice idea, but getting it setup will take a fair amount of work. It is all command-line based, and any firewall will take several lines of code to setup. Or even third-time users. And making changes is so painful that I don't want to get involved in doing them, even when I was testing a product last week that required some changes to my configuration. Like the Qube, it isn't worth trying to get this working for me.
Firewalls are good protection and make sense even for the average citizen.
But until the interfaces get better and the time it takes to configure them get shorter, they will remain curiosities for most of us. Sure, most of us need locksmiths to install locks on our doors. But it would be nice to add a layer of protection to our networks without having to hire expensive professional security consultants .
