I have also been experimenting with our home router recently and realized that they can provide a limited set of controls of what goes through the network. If your friend has a router that has a web-browser configuration page he may be able to do such things as block specific computers from accessing the internet at odd hours to blocking websites. While there are many ways to bypass these controls a ten year old might not have enough technical knowledge to want to bypass this general deterrent.
In addition, within the Mac system preferences Parental Controls can be enabled for individual accounts. If properly configured this could allow for a greater (if not perfect) degree of control of the child's computer usage. All of this does require practice, but might be a good place to start without having to invest in third party software.
