System calls from PL/SQL stored procedures

I would like to set up web pages (generated by PL/SQL packages) with forms that will pass parameters to SQLLOADER, IMP, and EXP. I know that I can use DBMS_PIPE on the PL/SQL side to send the commands, but I need a daemon that will receive the commands and issue the system call. I do not have "Programmer/2000" (Pro*C), so I need a program that can listen and send through a named pipe, without the Pro*C libraries. I've written mountains of C, but never a daemon. Does anyone have C source (preferable gcc) for a daemon to do this kind of thing, that they are willing to share?

Thanks.
