Unfortunately I don't have control over the processes that I am
running (they are components of a much larger system that I am trying
to bring under one roof).

However, it seems that a named pipe might work. Is it possible to set
up a named pipe for a process that I start and tell that process to
direct all its output to it?

Thanks,
