  Highly dynamic magnetospheric perturbations in neutron star environments can
naturally account for the features observed in Gamma-ray Burst spectra. The
source distribution, however, appears to be extragalactic. Although
noncatastrophic isotropic emission mechanisms may be ruled out on energetic and
timing arguments, MHD processes can produce strongly anisotropic gamma-rays
with an observable flux out to distances of around 1-2 Gpc. Here we show that
sheared Alfven waves propagating along open magnetospheric field lines at the
poles of magnetized neutron stars transfer their energy dissipationally to the
current sustaining the field misalignment and thereby focus their power into a
spatial region around 1000 times smaller than that of the crustal disturbance.
This produces a strong (observable) flux enhancement along certain directions.
We apply this model to a source population of ``turned-off'' pulsars that have
nonetheless retained their strong magnetic fields and have achieved alignment
at a period of greater than 5 seconds.
