Director of technology in a big international school here. Several points need-a-clarification.
#1: so, so many parents are so, so different. We once held one of those "parent internet safety" workshops. We asked 15 mom's, "what would you do if you walked into your kids workspace and saw them quickly minimize a window". Guess what? We got 15 different answers, ranging from "death" to "ignore".
#2: We have several parents who simply need the technical
skills to understand stuff like open dns and blocking at the router. We installed filtering software for them, and spend quite a bit of time helping them understand how to use these tools. see point #1, some parents need boku-blocking, other, none.
#3: the argument that parents should be watching their kids 24/7 to monitor and supervise their internet usage is bullshit. I've got a 2 year old, and I barely have time to keep my house clean. That being said, we use this safety PACT
becuase many parents don't even know how to set rules with their kids about internet use in the house.
#4: we teach parents about safe search, and spend so much time talking about profiles, and helping parents talk to their kids about safe internet usage. This tool would be "another tool in the belt" for us folks in schools. Guys, parents aren't geeks, eh?
