Of all the various parts of the brewing process, I REALLY don't think this one is enough of a hassle to warrant "fixing". It takes all of 2 seconds to drop the IC into the kettle, and about the same to lift it back out.
If you have it permanently mounted, the amount of extra time it will add to cleaning will be enough to make it a waste... And not only that, how would you be plumbing it - do you want tubing dangling off the side of your keg, or would you want it to be removable?
And that's not to speak of the expense and hassle of the bulkheads or whatever that you would need to use to actually mount the thing to the keggle.
I'm all for DIY projects, but I think you should seriously consider focusing your efforts on problems that are actually significant - this one just sounds like a solution waiting for a problem (no offense).
