Drew,. I agree completely if we use your definition of 
ontology-merging.  Partial mappings have a greater
success (particularly allowing heuristic mechanisms), and of course 
there's no reason we can't have some human in the loop.  Also, none 
of the literature I know allows instances to be mapped against 
multiple ontologies, which is a new idea that occurs easily on the 
Semantic Web, and which opens many opportunities for new research.
  So I guess I'm kidding myself
