  Experimentally have we got what it takes to pursue the direct observation of
WIMP interactions down to sensitivities of a few events /100 kg/year? For a Ge
target with a low energy threshold (<20 keVr) this corresponds to a
WIMP-nucleon sigma~10^-46 cm^2. A number of recent theoretical papers, making
calculations in SUSY-based frameworks, show many (>5) orders of magnitude
spread in the possible interaction rates for models consistent with existing
Cosmology and Accelerator bounds. Some theorists, but certainly not all, are
able to generate models, that lead to interaction rates at the few /kg/day that
would be implied by the current DAMA annual modulation signal. All theorists
demonstrate models that generate much lower interaction rates. This paper takes
an unashamed experimentalist`s view of the issues that arise when looking
forward to constructing 1 tonne WIMP detectors.
