Is there any way to track dupliverts?
nope
but you could track any real object, so you could simply make a real object there a child I guess of the face [same way you’d do a vertex parent, cept with 3 verts instead of one]
so, uhh, to do a vertex parent:
in edit mode on the mesh, select the vert(s)
control+rmb select the object you want to be the child
press control+p
