It only requires jQuery 1.2+, can be fully customized and handles user interaction without pain.
The way the plugin works by default, it’s aimed to always get permission. Users have the option to stop browsing or use a cookie blocker in their browser. I think this is useful to avoid loosing any useful cookie functionality we may be providing or having to reengineer the site. After all, we aren’t doing anything evil with the cookies, right?
That’s what I’m using in my web sites and I think it can be useful for anyone as an easily pluggable solution.
