It's not currently possible for an ipelet to get a pointer to other 
loaded ipelets.

I also don't think that would be very useful for you - qvoronoi simply 
unpacks the Ipe objects, calls the qhull code to compute the Voronoi 
diagram/Delaunay triangulation, then repacks the output as Ipe objects. 
  You can simply call qhull yourself if you need a Delaunay triangulation.

I'm afraid that is not the case.  Volunteers are welcome :-)
