Due to some past inapproriate behavior, yesterday I was monitoring my young nephew's online activiites. I logged onto his computer and saw a mouse pointer moving and the desktop image that's on his computer. When asked about his being online, he insists he was not on the computer but was using the internet connection on his portable gaming device. As I understand it, this would mean that a.) I would have to have put logmein on his gaming device, and b.) I was viewing what he was viewing on his device--but what I saw was definitely his desktop screen and a mouse pointer moving.
Is it possible that when I log onto his computer with logmein that I would see what he's seeing if he's on his gaming device if it's sharing his computer's internet connection? If what he says is true, wouldn't I see the screens of any other devices in the household that are using the internet connection when I log on with logmein? And wouldn't all of those devices have to have logmein installed on them in order for me to view those screens? Any confirmation of my suspicions is appreciated.
