Query: Interfaces in hot gauge theory   The string tension at low T and the free energy of domain walls at high T can
be computed from one and the same observable. We show by explicit calculation
that domain walls in hot Z(2) gauge theory have good thermodynamical behaviour.
This is due to roughening of the wall, which expresses the restoration of
translational symmetry.
