I agree. I think that I have a tendency to give parents access to this type of information much more than many on HN, but you have to do it at the right endpoint: the computer and network a child uses to access the internet. Parents need to install a network appliance that can analyze and present all of the activity that occurs on their network (i.e., a good router). I'm surprised that these are not yet widespread. I would be interested in creating one if someone wants to invest money.
