Parental Controls Device

[jm952370]

would this device work for the concept of some kind of parental controls unit?

i am looking into the possibility of connecting a pine 64 to a modem/router and then creating some kind of web interface that would allow parents or adults to

control blacklists
filter/block webistes like facebook during homework
schedule internet access for certain devices during certain hours of the day
an option to disable the internet for certain devices

would be interested to hear peoples views
