  If low energy supersymmetry is realized in nature it is possible that a first
generation linear collider will only have access to some of the superpartners
with electroweak quantum numbers. Among these, sleptons can provide sensitive
probes for lepton flavor violation through potentially dramatic lepton
violating signals. Theoretical proposals to understand the absence of low
energy quark and lepton flavor changing neutral currents are surveyed and many
are found to predict observable slepton flavor violating signals at linear
colliders. The observation or absence of such sflavor violation will thus
provide important indirect clues to very high energy physics. Previous analyses
of slepton flavor oscillations are also extended to include the effects of
finite width and mass differences.
