  We show that in the presence of a distance dependent Lorentz-violating
time-like background one may find superluminal neutrinos at some high energy
such as OPERA's scale. The similar behavior but approaching the subluminal
branch is found to appear for inflaton field in the low energy scale. Thus this
scenario seems to be suitable to acomplish both superluminal neutrinos and dark
energy.
