Everyone has a slightly different view of this, and I think yours as as 
good as any.  Dino and crew set out to tackle a very specific and well 
scoped problem, which really had very little to do with what many people 
believe is the IP/loc split.  They were out to change the nature of the 
performance curve by adding an additional tier of routing that is 
bilateral in nature rather than multilateral.  To me that's the 
fundamental challenge.  IDs and locators are not a central them in LISP, 
IMHO.  And for that matter, neither is whether you tunnel or map 
(although each has its advantages).
