First, child services has been called on multiple occasions and has done nothing. The police don't care either. They're disabled so they can't just leave.
They have a laptop that they can use whenever they want but their patent is extremely opposed to piracy and won't pay for my friend to buy movies or a streaming service. They watch DVDs from the library on their laptop.
They're also not tech savvy so I need a plug and play solution that will allow them to pirate media without anyone else in the household being aware of it.
I would also recommend tailscale to make setting up the server connection easier. Just send your friend a link Tailscale gives you and she can connect her computer to yours without any port forwarding or what have you.
