Hi John - We can do distributed computing manually using pipes, works
great in multi-core processor, and slower data paths can be run
between machines across a network using sockets.  There was discussion
once about automatic load balancing across cpu cores / machines.
But you can have one script use a file sink to a fifo, and another
script use the same fifo for a file source - works great.
