The author seems to be talking about parallelising the actual crypt()
algorithm, to do a single crack accross many CPUs, and maintains it's
like 9 women trying to produce 1 baby in 1 month :-)

So perhaps a bit of mis-information on his side about parallelising 
operations? When he could simply run multiple instances of crack accross
a network like you describe, a good oul bit of data/domain decomposition, 
maybe put an MPI wrapper round it to collate results or nicey it up 
for running it from a head node accross a cluster - that's maybe what
people were requesting from him and he mis-understood.
