Pipes on the Amiga are really much simpler than you think (I think :-) ).
Just pretend they are files.  Then, instead of something like:
	pipe_handle = popen("command", "w");
you would do
	pipe_handle = fopen("pipe:myfile", "w");
	Execute("command <pipe:myfile", 0L, 0L);
and voila.  You probably want to use mktemp() to generate your pipe
file name, just to be safe.
