I setup an Application Cache on a site and shortly thereafter realized its way more aggressive that I realized. I want to remove it. Permanently.

If you just want it removed from your side you can do that from the Browser. I can only remember how to do it in Chrome. Go to chrome://appcache-internals/ & remove desired file(s). You can also clear cache & cookies & that should work. I've only testing that in Chrome, however.
If you want to remove it for all viewers, I know of no way to detect if they have an old cached version, but I know that keeping the attribute with a false link, like Maurice suggested, would be the only way that I would know; though, I'm sure there is another way, most likely with jQuery.
