Is the realizability in 3-space correlated to the amount of symmetry the combinatorial polyhedron has -- size of symmetry group, vertex/face transitive symmetry? I think more symmetry may mean the triangulation is easier to put in 3-space, so one might want to look at very un-symmetric triangulations.
