I would like to add my 2 cents.  I have not seen RPD yet, but one of the
better examples of a VTK pipeline editor is the VISSION system[1] by
Alex Telea[2].  It blows most other network editors out of the water, as
wrapping VTK represents only a single case study for VISSION.  The
system has been used to wrap other large C++ toolkits as well.

Alex solved the introspection issue in an entirely generic (and
therefore universally applicable) fashion by making use of a C++
interpreter and Alex's metaclass concept.

The only disadvantage of VISSION is that it's not publically available.
:)  However, the way in which the C++ introspection problem was solved
is available and has been proven to work exceedingly well.

Personally, I would just do it via Python a la vtkPipeline (by Prabhu,
based on work by Paul for Tcl), but then that's me. :)

keyword VISSION, there are at least 4 articles)
