Great thread!
SheriffNZ: I read about this one on the New York Times. It was used by some IT guy. Other than that, I don't know anything about it but it adds another option.

I looked into that. They made no guarantees it would work in NZ, but to give them credit they were prepared to give it a go if I bought one. I was prepared to do that but their support dissappeared for about 3 weeks, and during that time I'd gone with an alternative (see below). Also when a site is blocked it puts up a whole lot of "Safe" disney links.
The other device I went with was a Koalasafe. http://www.koalasafe.com. We have a range of items on our network, ipads, pc's, chromebooks, iPhones and Android phones. We don't want to protect all those devices, but we do want to block the chromebook, for which there is very little software around that does this effectively. It's designed and shipped from Australia, under active development. Shipping took a while for a number of reasons, but kudos to the support team for keeping us updated throughout the whole process
The KoalaSafe device plugs into your router and sets up another wireless network. You just set the devices you want to protect to use that network and away you go. Setting restrictions on the device is done through a mobile app. You can set time limits, add sites, check sites visited, even add extra time or reduce time as required. If you prefer you cn use some of the preconfigured groups and apply them to a users profile.
Profiles can have two lots of settings applied - so you could say homework gets done between 3 and 5pm and only allow acess to homework type sites, and then playtime happens between 5pm and 6pm and allow an expanded set of sites. There's a bit of flexibility but I haven't been able to figure out how to use the same device with two different people / profiles.
Has it helped us? Yeah, I'd say so. We always used to have robust discussions when internet time was up, temper tantrums and the rest. Now that never happens. There is the odd request for extra time and we can give an extra 5 mins easily via the app, and then say enough is enough. There's less stress in our family for it, and we can easily monitor and have discussions about what sites are visited.
It's not the cheapest option but we have two more kids to go through learning how to be safe online, so we figured over that time it would provide enough value to pay for itself.
