What you ask for is clearly impossible because the lines 
in the two columns are not held in registration.  However, if
you only want a ruler or a column of numbers -- not *line*
numbers -- then that looks feasible.  I don't know of a 
packaged solution, but one could be concocted if it doesn't
exist already.  

On the other hand, it is probably not too difficult to modify
lineno to supress one set of line numbers.
