Unused? I 'm afraid that I don't quite understand you... How does it affect
 ipfw functionality?

You know, I am the real ipfw newbie, but I am using pipes during about
5 months. I do ipfw flush quite often (I like to play with that tool
:)) , but never did "ipfw pipe delete", and never noticed nothing strange
in pipe behavior. Now I am quite confused? Are you sure, that doing
"ipfw flush" does not delete the pipes? May be FreeBSD guys should add
"ipfw pipe delete" line to standart /etc/rc.firewall, just before the
"ipfw flush"? IMHO this will save many newbies from confusion ;)

Good luck
