I don't know how Windows shells deal with piping, or even if they can. All I know is that DOS used to simulate it with temporary files, lacking any real multitasking.
Windows has proper pipes these days, and System.Process.runInteractiveProcess creates pipes for you.
But it is not suitable for this purpose. It returns Handles, but it doesn't let me specify Handles going in. That means that it is not possible to create a pipe going directly from program A to program B. -- John
