OpenBSD has asked for donations: "To fulfill most development goals OpenBSD should be generating about $100K USD. With that amount of money the project can finance 1 large and 4 small hackathons per year. Pay the bills and a part-time developer to mind the shop when Theo isn't around. In an ideal world we would have a sponsor per hackathon and the CD sales would be paying for other expenses." On a very related note, pre-orders for OpenBSD 3.9 are now available.
