Query: Generalized 2d-dilaton models, the true black hole and quantum
  integrability   All 1+1 dimensional dipheomorphism-invariant models can be viewed in a
unified manner. This includes also general dilaton theories and especially
spherically symmetric gravity (SSG) and Witten's dilatonic black hole (DBH). A
common feature --- also in the presence of matter fields of any type --- is the
appearance of an absolutely conserved quantity C which is determined by the
influx of matter. Only for a subclass of generalized dilaton theories the
singularity structure vanishes together with C. Such `physical' theories
include, of course, SSG and DBH. It seems to have been overlooked until
recently that the (classical) 'black hole' singularity of the DBH deviates from
SSG in a physically nontrivial manner. At the quantum level for all generalized
dilaton theories --- in the absence of matter --- the local quantum effects are
shown to disappear. This enables us to compute e.g. the second loop order
correction to the Polyakov term. For non-minimal scalar coupling we also
believe to have settled the controversial issue of Hawking radiation to
infinity with a somewhat puzzling result for the case of SSG.
