Been planning to do this for my family as well. But after my (admin) passing, and with multiple children sharing the same domain name, one of my children will have to be the domain admin for everyone in the family. This might be fine if they remain in good terms and have enough trust of the admin to not screw their primary online identity...

I have yet to figure this part of the equation out.
