Ask HN:Facebook “Like” button hiding content on a non Facebook site?

Do you know if its possible to have a Facebook “Like” button hiding content on a non facebook site?<p>Eg we know it’s possible to hide content on our fbml frames within Facebook eg www.Facebook.com/LiveBaseballChat but what i want to know is it possible to block the view of someone seeing non Facebook content unless they like a related page?<p>Eg can I have an image “hiding” the video or chat iframe on the www.LiveCourtChat.com page unless someone clicks a “Like” button for the www.Facebook.com/LiveCourtChat page?<p>Cheers,<p>Dean
