I think that we should differentiate between characters acknoledging the viewers, and full interaction through the fourth wall;
No examples for 'Beyond Fourth Wall'? Without a more solid definition, people are just going to use it as a hyperbole for other categories.
Repost from the Archive, to make clearer why they're the only examples provided: Bob And George and One Over Zero aren't in any way special; they're listed purely for illumination, rather than specialness. If you can find a better pair of examples that theoretically go in the same region of this scale, but one is clearly further down the scale than the other, go ahead and replace them.
