  We study opportunities for future high-precision experiments in kaon physics
using a high-intensity proton driver, which could be part of the front-end of a
muon storage ring complex. We discuss in particular the rare decays
$K_L\to\pi^0\nu\bar\nu$, $K^+\to\pi^+\nu\bar\nu$, $K_L\to\pi^0e^+e^-$, and
lepton-flavour violating modes such as $K_L\to\mu e$ and $K\to\pi\mu e$. The
outstanding physics potential and long-term interest of these modes is
emphasized. We review status and prospects of current and planned experiments
for the processes under consideration, and indicate possible improvements and
strategies towards achieving the necessary higher sensitivity. Finally, we
outline the machine requirements needed to perform these high-precision kaon
experiments in the context of a muon storage ring facility.
