  Continuing the development of the ZSM-Newton/Coulomb approach to
semiclassical Newtonian gravity/electrodynamics [1], we formulate a
ZSM-Newton/Coulomb version of the large N approximation scheme proposed by
Oriols et al. [2]. We show that this new large N scheme makes it possible to
self-consistently describe the center-of-mass evolution of a large number of
gravitationally/electrostatically interacting, identical, \emph{zbw} particles,
without assuming that the particles are weakly coupled, and without entailing
the problematic macroscopic semiclassical gravitational/electrostatic cat
states characteristic of the mean-field Schr{\"o}dinger-Newton/Coulomb
equations. We also show how to recover N-particle classical Newtonian
gravity/electrodynamics for many gravitationally/electrostatically interacting
macroscopic particles (composed of many interacting \emph{zbw} particles), as
well as classical Vlasov-Poisson mean-field theory for macroscopic particles
weakly interacting gravitationally/electrostatically. Finally, we outline an
explicit model of environmental decoherence that can be incorporated into
Oriols et al.'s scheme as applied to ZSM-Newton/Coulomb.
