# o OpenBSD team wants to get changes incorporated into IPF. Darren no
#    respond.
# o Ask again -> No respond. Darren coder supreme.
# o OpenBSD decide to make changes, but only in OpenBSD source
#    tree. Darren hears, gets angry! Decides: "LICENSE NO ALLOW!"
# o Insert Flame War.
# o OpenBSD team decide to switch to different packet filter under BSD
#    license. Because Project Goal: Every user should be able to make
#    changes to source tree. IPF license bad!!
# o Darren try get back: says, NetBSD, FreeBSD allowed! MUAHAHAHAH!!!
# o Theo say: no care, pf much better than ipf!
# o Darren changes mind: changes license. But OpenBSD will not change
#    back to ipf. Darren even much more bitter.
# o Darren so bitterbitter. Decides: I'LL GET BACK BY FORKING OPENBSD AND
#    RELEASING MY OWN VERSION. HEHEHEHEHE.
