   I should add that your scheme of adding rather than subtracting the   
   delayed RIN will work over a narrow band at a frequency of 1/delay, but   
   that the etalon fringes will probably do a good job of making that not   
   work very well.  You might get 30-40 dB if you're lucky, which might be   
   enough.
