Sometimes you can get by without knowing the actual coordinates of a 
point, using "\SpecialCoor". Thus to draw a line joining an "rnode" and 
a point 1 in to the left of it (if I read your problem right), you can try
	
	
	\rnode{a}{N}
  	\SpecialCoor
  	\psline[unit=1in](a)([angle=180,nodesep=1in]a)
