Hi Hannu,

I agree that the mapping itself is a critical part of the  
architecture. However I believe a mapping proposal needs to go  
together with an overall architecture, because one needs to know where  
mapping happens, mapping what to what.
Take a simple example: ILNP has kind of mapping (implemented in DNS)  
and LISP has another kind of mapping, 2 different proposals have  
rather different mappings.
