My take on all this is people spend 5 minutes thinking about it and are 
confident they know it all.

A few years back some hacker claimed they'd gotten into the Boeing flight 
control computers via the passenger entertainment system. I don't know the 
disposition of this case, but if true, such coupling of systems is a gigantic 
no-no. Some engineers would have some serious 'splainin to do.
