This seems like it would be much easier as a feature on your router/access point.
Their description suggests that it's just using a blacklist of MAC addresses so it would be pretty easy to add to something like OpenWRT or a captive portal.

This is the kind of stuff that allows "muggles" to do stuff without having to be bothered calling an IT person. I'm not a fan (I can foresee many wasted hours of IT professionals trying to debug a network that's "working funny" because the owner plugged one of these without telling anyone), but I can see it being popular among small business owners.
