A new architecture with a new namespace could mean that we have to change
most of components of current Internet. It is a revolution rather than a
smooth transition.

For example, HIP, it requests ALL end devices change their stacks, ALL
applications to be modified in order to support HIT, and to deploy a global 
mapping real-time system in order to translate the identifier (HIT) into
locator (IP). I am sure that I do not mention all the costs. Personally, I am pessimistic the abovementioned can happen in a short future. HIP does not 
improve the network routing however. HIP++, Node ID even requests more in
order to optimize network routing. It consequently requests the modification 
on all the routers besides all the abovementioned requirements. Is it
expensive?
How is this cost any higher than that of deploying IPv6? It seems to me that there's no significant qualitative cost differentiation between deploying v6 as it stands today and some better solution. In fact, a better solution might well be easier to deploy, as the cost/benefit ratio might be tolerable. 

Tony, the work's been done for IPv6, for most infrastructure products
and a quite large chunk of applications. Good luck in asking development
managers to start over. Unfortunately this is orthogonal to the
better/worse discussion.
