Talking of *nix security, have you guys heard back from the guys at gluck about the hacked debian server (see http://www.linuxsecurity.com/content/view/123560/65/). I think it goes to show that no matter how secure an OS is claimed to be, the security is in the user, not the OS. Users need to understand the underlying OS to make it truly secure (although I can imagine the guys who run that particular server are very good at their jobs).

PS - Don't get me wrong - I'm a keen kubuntu linux fan.
