  In the high-temperature phase of QCD meson spectral functions at nonzero
momentum are expected to have a nontrivial and interesting structure. In order
to provide a reference point for lattice studies employing e.g. the Maximal
Entropy Method, we discuss several characteristics of meson spectral functions
in the infinite-temperature limit. We report on ongoing work in quenched QCD
with staggered fermions.
