I did some experimenting with GOP level parallelization some time ago,
the idea being to run it on a network.  I never got quite that far,
but I did get a rather nice performance boost on SMP.  The catch was
that the resulting bitstream wasn't quite correct.  That could've been
fixed, but I got involved with other projects instead.
