Ok, here goes, I think my unfamiliarity with the notation is confusing things. I'd like to write a view of users that user a (who is the manager of a group) and user b (who is only a member) can use. In that view I want a and b to see {a} and {a,b} respectively. I thought I could write that view in an extensible way using the lookup-resources API by using one permission,

view_member

, but couldn't figure out how to, hence my question.
