Idea's for banner ads...

Three idea's for banner ads I would love to see in order by personal preference...

Link an ad display to user logon or lack thereof... My site content sits behind a paywall and one of the biggest complaints I get is "Hey you posted a link to this article on facebook but the article sits behind a paywall!!!" I know I can bypass the paywall in the article's custom properties but I'd like a way to monetize that. For example if a non-subscriber opens an article then display the ad in the popover position. However never display the popover ads when a subscriber is logged in. (So there would be 3 states "logged in subscriber," "logged in non-subscriber," "not logged in" --- by default an ad would display under all three circumstances... by deselecting one or more options on the ad setup this would be controllable. 

Link Ads together... I would love the ability to link 2 or more separate ads together (related) so that when 1 displays they both do... For example a skyscraper, leaderboard, and background ad (page takeover)

Smarter exclusions ... say I have 2 skyscrapper ads and I'd like them to randomly switch between 2 ad positions... If I put both ads in both positions then it randomly selects which ad will run in each position ... Because the same ad can't run twice on a page sometimes I see both ads some times I will see one ad... I'd like the system to be smart enough to say "Hey this ad is already running elsewhere on the page I'm going to automatically select the other ad for this position."
