  Lattice QCD has the potential this decade to maximize the sensitivity of the
entire flavor physics program to new physics and pave the way for understanding
physics beyond the Standard Model at the LHC in the coming decade. However, the
challenge for the Lattice is to demonstrate reliability at the level of a few
per cent given a past history of 10-20% errors. The CLEO-c program at the
Cornell Electron Storage Ring is providing the data that will make the
demonstration possible.
