So, my interpretation of your views is that in the short term there will be
upward pressure on the size of router table due to provider inexperience and
distraction, but in the longer term these inefficiencies will be swept away
by the consolidation of providers due to the commoditization of global
communications.  Is it reasonable to think that significan consolidation
will happen over the 15 years?

Imagining, just for the sake of argument, that the ensuing oligopoly is
represented by 12 'super' providers and a few thousands of niche, value
added, local providers....what then would be the impact on the router table
given common practice (BGP)?
