  The importance of future studies of charm and $\tau$ decays is emphasized as
probes of New Physics: the most powerful tools are \cp asymmetries in charm and
$\tau$ decays both in partial widths and final state distributions. While these
searches for \cp violation are instrumentalized in the search for and hopefully
future analysis of New Physics, they might also shed light on the \cp breaking
dynamics required to implement baryogenesis. $e^+e^-$ Super-Flavour Factories
are optimally suited for the challenge, in many aspects even uniquely so.
