  Motivated by the recent work of Wang, Lin, Pavon, and Abdalla [1], we
generalize their work to the non-flat case. In particular, we provide a
thermodynamical interpretation for the holographic dark energy model in a
non-flat universe. For this case, the characteristic length is no more the
radius of the event horizon (R_E) but the event horizon radius as measured from
the sphere of the horizon (L). Furthermore, when interaction between the dark
components of the holographic dark energy model in the non-flat universe is
present its thermodynamical interpretation changes by a stable thermal
fluctuation. A relation between the interaction term of the dark components and
this thermal fluctuation is obtained. In the limiting case of a flat universe,
i.e. k=0, all results given in [1] are obtained.
