Jim wonders if a VPN is really worth it for daily life, and can it be used to control the content his kids watch? Leo says maybe not. But Leo says that OpenDNS certainly can. It enables you to filter content so that kids can't go where you don't want them. A VPN is used to carve out a tunnel online so that others can't see what you're doing. So it's the opposite. But OpenDNS is great for protecting your kids from the stuff out there. A new router can also do the same.
