I'd say yes.  You are too optimistic.  :-).

Well, yes.  Of course.  If you make the routing locator also be the  
endpoint identifier, then _of course_ you must deal with the  
topological significance of the endpoint identifier.  It sort of  
follows.  You can't have your cake and eat it too.

Unfortunately, I do not believe a host-based solution like shim6 will  
ever be operationally deployable as it requires a rewrite of kernel  
stacks and such.  I'm told people are already deploying IPv6 stacks  
that do not support the "mandatory" IPSEC goop and there is an  
expectation stack developers are going to tack on an optional bit of  
black magic that is used only in very rare circumstances?  I have to  
admit some skepticism.
