Nope--I would only have come up with "the traditional view" (that
antidromic conduction is a crime against nature).

So I did a literature search.  Rob or Stephen, if you can handle a 4MB
.pdf file, I can send you the article I found:

  Pinault D.
  Backpropagation of action potentials generated at ectopic axonal loci:
  hypothesis that axon terminals integrate local environmental signals.
  [Review] [484 refs]
  Brain Research - Brain Research Reviews.  21(1):42-92, 1995 Jul.

I've only skimmed it.  Pinault suggests that retrograde firing might:
1) help a neuron synchronize rhythmic firing from its inputs, 
2) potentiate synapses, or 3) provide a quick way to send an error
signal backwards.
