Query: Sensitivity of pp-Bremsstrahlung to Meson-Exchange Currents   We present pp-bremsstrahlung cross section calculations at the
$\pi$-production threshold to search for kinematics that best differentiate
model-dependent descriptions of the NN $t$-matrix and accentuate the
contributions of isoscalar meson-exchange currents. Existing optimization
procedures are shown to be completely unreliable due to the neglect of
meson-exchange currents and phase space variations. We show that phase-space
hides the most important differences in model $t$-matrices, but that improved
data will be critical to further investigations of exchange currents.
