Please see the implementation report on the IDR wiki at:

You will find information regarding the bgp open policy implementations.  I'm glad to discuss these implementation reports with you.  You can query the authors of this draft or the implementer forms. 

Cheers, Sue

   I know it's late and this draft was already asked for publication (congratulations). I think this is a terrific job and I can  imagine different scenarios.

   I wonder if there is already some working code somewhere?, probably some beta code for quagga, frr, etc?.
