Alas, but simple ideas are not always right.  The data also indicate that that
there is an absence of weak sources, i.e., if you plot the intensity 
distribution that you expect for a uniform extragalactic halo, you find
that the data drop off too quickly after a certain intensity minimum.  It's
as if there are no *far* bursters, even though they are uniformly distributed
in the sky.

This suggests, at best, an in-between solution - bursters are associated
with our galaxy, but are uniformly distributed in a sphere.  There are problems
building such models as well, but I can't remember the details off the top
of my head.
