Ok, with all of the activity in the Atlantic and the Gulf, I have to stop being nice by just hoping that people will use the kmz instead of the kml. So here's what I've done.
1.) Not changed the kmz network link.
2.) Crippled the kml link by displaying a single Placemark that shows you how to use the kmz instead.
Now, I didn't want to do this at first, because it seemed that some versions of the GE client didn't like the kmz link very much. I'm hoping that all the subsequent versions have fixed that problem, and urge you to update to the latest version if you indeed have this problem. Other than that, my thinking was that it's better to be able to provide this info to those that are willing/able to use the kmz link rather than to not be able to provide it at all. Like I've said before, the Kmz provides identical functionality to the kml, so it should be transparent to those familiar with this Network Link. I'm actually upgrading my client as I type this because the version I had didn't play nice with the kmz network link, so keep your fingers crossed.
I probably need to eat something before the night is over, but I'm looking at a couple of the other things on my list above to see if I can squeeze them in tonight.
