I was reading an article today in ComputerWorld about something called KSplice, which allows Linux users to install critical updates and patch in without rebooting the computer. I tried it and while it was a bit odd for installing (not auto-disabling the Ubuntu update system), it worked very well. I think something like this would be great for Fedora as well, possibly something for Fedora 12.

Would it be possible to implement this or something similar for Fedora?
