I think Juanma is trying to say two things: If we want to use the
display margin in order to display something on each line, we have two
options: text properties and overlays.  Neither one of them seem
appropriate.  Therefore, first first question is: How can something be
displayed on each line?  RMS seems to think that the only appropriate
solution is on the display level, ie. C.  The next point Juanma is
raising here, I think, is this: If we cannot use the display margin to
display something on each line from the lisp level -- what use is 
lisp access to the display margin.  I guess he'd like to see some
examples of good use of the display margin.

Anyway, that's how I understand it and the points seem valid enough --
if Juanma didn't intend to ask the above questions, then I intend to.
