  Employing a previously derived formulation, and extending the treatment from
purely transverse modes to wave vectors having a longitudinal component, we
discuss the prospects for the occurrence of Weibel-type color-current
filamentation in high-energy nuclear collisions. Numerical solutions of the
dispersion equation for a number of scenarios relevant to RHIC and LHC suggest
that modes with (predominantly transverse) wave numbers of several hundred MeV
may become moderately agitated during the early collision stage. The emergence
of filamentation helps to speed up the equilibration of the parton plasma and
it may lead to non-statistical azimuthal patterns in the hadron final state.
