yea you can share as far as I know... I sold a laptop and craigslist, without formatting the HD (I had only used it for a day or two - so very little real info was on there). It didn't have my Netflix password saved, but it was a "trusted device" or whatever Netflix calls them... So for about a month movies were showing up in my "recently watched" area that I had never seen. Removed the laptop as trusted and it hasn't happened since.
