  There has been significant recent experimental activity on the related topics
of charm mixing and rare (flavor changing neutral current) decay. For mixing,
several new results from direct (wrong sign) searches and first results from
lifetime difference (Delta Gamma) searches have been reported. Limits for r_mix
of approximately 5 x 10^{-4} (or better) are possible from work in progress.
For rare decays, sensitivities to branching ratios are now at the level of a
few x 10^{-6}.
