it is interesting to watch this series of exchange between Paul and  
Robin:)
One position states that we face serious routing scalability problem  
today.
another position states that insufficient evidence exists today to  
support the above.

If I take on a 3rd position: this debate seems a supporting evidence  
for what we discussed at Hiroshima meeting (see my presentation on  
behalf of the evolution solution team, http://www.cs.ucla.edu/~lixia/aggregation.pdf 
, slide 4),
- Internet is big and diverse -> routing scalability problem
   is not universal
- Internet has no boss -> no universal buy‐in, no flag day/year/decade

Thus we need solutions that can be deployed by individual parties who  
need it, and can provide clearly identifiable returns (slide 5)
