No mapping is needed. Well, a routable namespace (as is used by TARA) could be the base for even time-of-day routing. Look, TV-multicast with millions of receivers e.g. multicasting a soccer final for 90 minutes would bring immense traffic load, which needs to be well-balanced. Today in Sueddeutsche Zeitung an article about smart grid powerline network mentions that Cisco sees a 100 times bigger network here to come compared with the internet. But so far, the reaction wrt TARA's abolishing the scalability problem even if it were 1000 times bigger was that the task is only to reduce the problem.

Note! This is an open question since I haven't studied the mapping solutions in detail -- patte Yes, LISP's distributed database is either no reduction of the routing churn (if too broad) and otherwise a huge polticial problem - both in case of a cyberwar attack as well as due to the potential threat as to decline service. The EU's Galileo initiative is not because GPS isn't good enough but because its service could be denied by the political owner. Imho, this is the most severe non-starter argument. Thank you for sharing this concern. Heiner
