OpenBSD's ports mechanism is a pretty cool way of building third-party software for OpenBSD. Like everything else, it's done by volunteers. Here's my little bit.
These are ports in the tree that I am maintainer of, although I am pretty much slacking on a few of them. I originated most of these ports (except junit which I took over). I wrote the program used in jeoip.
Too many to describe in detail. These are in every state of disrepair, from working and almost committable down to nothing more than a Makefile that records a download location I thought I might want to make into a port someday. Some of these are not even mine but are from others; I just put them in "mystuff" cause our current Ports mechanism has a severe allergy to e.g., creating an "othersstuff" directory.
Here's a list, created by
cd /usr/ports/mystuff; echo */* | fmt

Some of these are available for download; these are ports, not packages, and should be untarred into /usr/ports/mystuff to avoid conflicts with CVS in the main part of the tree.
