However, it is a pretty impressive piece of software, intended to apply security updates to a running kernel with a "hot-patch" approach. They give their latest status update here: http://lkml.org/lkml/2008/12/5/330 I like that they have the goal of following the entire stable tree, since it's not always clear which updates are security-related. Their work is currently licensed under a GPLv2, and they haven't thought very hard about whether they would be willing to relicense with a BSD license. (They're focusing their efforts on the Linux kernel, for the moment.) -Ben Kaduk (disclaimer: the Ksplice developers are friends of mine, so I heard most of this first-hand.)
