That would be a possible solution to the problem, yes.  Although I
don't know that it is the proper thing to do semantically.  If you
added this as a cursor-type, then you couldn't have my desired
behavior with the empty-boxes along with a bar cursor.  Unless you
want to extend cursor-type to include things like 
(selected-window . (bar . WIDTH)).

On the other hand, your comment on a list of buffers makes me think
that you didn't understand my proposition:

Proposition: Within the function of x_display_and_set_cursor,
instead of using the value of cursor_in_non_selected_windows, we use
its buffer-local value (if any) in the buffer of the window for which
we are drawing the cursor.  So, in order to get the effect I am
looking for, one has only to do the following when creating the

(make-variable-buffer-local 'cursor-in-non-selected-windows)
(setq cursor-in-non-selected-windows nil)

This proposition loses if we like the current behavior when making
cursor-in-non-selected-windows buffer-local, but I don't know that
anyone has even considered doing that, other than myself.
