yes, indeed.  of course, the devil is in the details.  

having a separate pseudo-header with routing locator, for use by the 
routing system seems like a useful approach (though not the only 
possible approach).  OTOH, based on what I've heard I've formed
the impression that there are scaling limitations with the way that 
MPLS tends to be used.
