How can I find out if a user has clicked the Facebook Like button on my website?

Question

I want to include content on my website which will only be displayed if the user has clicked the Facebook Like button on the very same page. I see in the documentation there is the "edge.create" event which I can subscribe to but won't that only fire when the user likes the page the very first time? If a user has already liked the page, I want him to be able to come back and download again without having to unlike and then like again.

I also notice that this information can be queried through FQL and the likes but it's not clear what the auth requirements are for this.

Is it possible to do this in some way without extra authentication? I want there to only be a single step for the user if he is already logged in.
