Undeadly.org has a review of “The OpenBSD Packet Filter Book“, which is Jeremy C. Reed’s version of the PF FAQ and other material, in printed form. It’s available through Lulu.com print-on-demand. DragonFly is mentioned in there, as we (along with I think pretty much every other BSD) also use PF.

Just to let you know, we are also having it printed by another printer (other than lulu) and is being distributed via normal online bookstores, like Amazon, also.
