Query: Gauge Symmetry of the Third Kind and Quantum Mechanics as an Infrared
  Phenomenon   We introduce functional degrees of freedom by a new gauge principle related
to the phase of the wave functional. Thereby, quantum mechanical systems are
seen as dissipatively embedded part of a nonlinear classical structure
producing universal correlations. There are a fundamental length and an
entropy/area parameter, besides standard couplings. For states that are
sufficiently spread over configuration space, quantum field theory is
recovered.
