Oh yeah. I know. I would expect for some-to-many minor things (like the TCP bug you mentioned), this wouldn't be an insane way to do a hot upgrade. Guess one would need to make a close study of the diffs.
Regardless, I mentioned the fact that this isn't a good idea for any novice who might stumble across this comment months or years hence and get the wrong idea. :)

Oh, CARP is so cool. It's a bit of a pity that ucarp doesn't support IPv6. But, how does CARP replace a load balancer? Isn't it used for single host availability, or is my understanding too narrow?
