I think there's some misunderstanding. Nothing has to know about X
endsystems. Nor did anything have to know about N routers before.
In the shim6 approach, a host only needs to know about its correspondent
hosts. From a scalability perspective, this is unchanged from
previously, only the constants are bigger.
