Some versions of 'syslogd' allow one to redirect output to a named pipe
(aka FIFO).  The program that creates and reads this FIFO would have to
start before any logging could be done, of course.  I'm not sure how
this would differ from just having 'named' write to the FIFO.

You would, of course, have to write a simple "wrapper" program that
creates the FIFO and either execs the program with the FIFO as stdin,
or forks and execs the program, and actively reads from the FIFO and
feeds the program.

Or you could copy the PERL script and modify it.  Works even if you
can't edit the original.
