In other contexts I've written about (using someone else's term but can't recall whose) airplane perspective which is when people are in a line and the person in the back can see everyone but each person as you move up only sees what's still in front of her.

Add to this, apartment building view. Here we have multiple viewers who are side by side and MORE OR LESS looking at the same thing but cannot see one another.

Related category is the view described by Bentham and Foucault vis a vis the panopticon in which one knows one might be visible but one cannot verify and one cannot see those who see oneself.

Other variations on asymmetric information exist. Has anyone ever cataloged them?

Standard distinction is between adverse selection (insiders know more than outsiders - asymmetry pre-contract) and moral hazard (if no one will find out, I won't be careful - asymmetry post-contract) and signaling (attempt to reveal private info imperfect).

Compare, too, by-stander effect logics and similar collective action problems.

More, perhaps, in the design of games?

Not sure if it is an idea that is a subset or superset of these, but think about role of information triads. Three way information asymmetry as the stuff of drama associated with notification (when audience sees that there is "inappropriate" information asymmetry among actors.
