Or, on top of that, how traffic engineering can be performed with shim6..

And people wonder why more "content" isn't available for v6. Maybe when 
content providers start asking for a /32 *per datacenter* (ie a /26 or so 
of initial allocation) those issues might get solved... then again, 
probably not.

(firmly in the shim6 does not adress *most* of the issues camp)
