I guess I don't understand the problem with passing it in the command
line. If it's a process-to-process communication, it won't be visible

As for using pipes - if you've never used them before, you're going to
need to do a fair amount of reading. The api's aren't complicated, but
handling errors without hanging can sometimes be tricky.
