  I'll describe a general geometric setup allowing for a generalization of
Rehren duality to asymptotically anti-de Sitter spacetimes whose classical
matter distribution is sufficiently well-behaved as to prevent the occurence of
singularities in the sense of null geodesic incompleteness. I'll also comment
on the issues involved in the reconstruction of an additive and locally
covariant bulk net of observables from a corresponding boundary net in this
more general situation.
