  It has been proposed that the entropy of any object must satisfy fundamental
(holographic or Bekenstein) bounds set by the object's size and perhaps its
energy. However, most discussions of these bounds have ignored the possibility
that objects violating the putative bounds could themselves become important
components of Hawking radiation. We show that this possibility cannot a priori
be neglected in existing derivations of the bounds. Thus this effect could
potentially invalidate these derivations; but it might also lead to
observational evidence for the bounds themselves.
