It is an interesting article but confirms a few things to me.  

1.  There are only a very small percentage of flapping routes causing an 
inordinate amount of BGP processing.  Would it be more effective to implement 
this route damping mechanism world wide or try to eliminate the source of the 
instability?

2.  The paper does not suggest how you would implement this on a global basis 
and what the "some people have it and some don't" scenario looks like.  The guy 
in the middle pays the price for your unstable customer.

3.  This affects such a small subset of global routes that we should be 
spending our time solving more globally impactful changes to BGP (like path 
bandwidth awareness).
