Damien Bergamini (damien@) just committed WPA-support (wikipedia) for OpenBSD. In the commit message, Damien states that "bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4), rum(4), upgt(4), and zyd(4) should work." And, Damien says "support for more chipsets should arrive soon."To me this is of more significance for folks that build wireless routers than anything else.
But what do I know/care. Although truth be told I wouldn't mind running PF as my home firewall if the USB EVDO card would work.
