Really works for the smarties eggs, they are just overweight smarties.

Back to the days of rip out the head unit and stick one in that does have the features you want?

I wouldn’t describe most of that as hacking. Reads like sudo larping drivel to me.

Do they need to be separate logins if they are to access the same files and connected device(s)?

Just a Machine01 account with access to a shared drive or OneDrive for backup would do it wouldn’t it?

If the machine is only used locally then limit it’s access to the internet so people have to actually login to access/download anything and treat it as part of the equipment it’s attached to.
