The problems are there anyway.  They are not removed by
putting dispatchers and a Web service access point in front
of the distributed objects.

If you get rid of the dispatchers and just interact directly with
Web resources which deal in representations of externally-
facing business objects, you just removed one or more
layers of complexity, but you still need a mediation layer
between the internal object and the external resource.

As Peter Furniss says now and then, there is a fixed 
amount of complexity involved in this problem, and 
you can move the factors around and add unneccesary
factors, but you can't remove the essential ones.
(Peter says it better, but I can't remember his exact words...)

(But not all factorings are equal...)
