Develop a faster solution to the Facebook Like Button Event handler

I'm looking for a faster alternative to know when someone hit the like button that exist on my site. Currently I'm using the [login to view URL]('[login to view URL]') to get notified, but the response is sent about 3-4 seconds after the user hit the Like button. I need a solution to instantly know when someone hit the Like button? The second you click on the Like button, the Comment box is opened as default which well exceed the boundaries of the original Likebox iFrame. Maybe there is a way to Listen to that event (though I believe the commend box is in its own iFrame). Or maybe there is an option to listen to a click inside the iFrame (like getting the current coordinates of the iFrame and that of the mouse cursor and track the click if it happened in pre-defined coordinates. Though a click isn't a guarantee the user actually Liked the page, its good enough for my needs in this specific case. The solution should be in form of a piece of code to be pasted in every page that has a standard Facebook button and that acknowledge the user "liked" the page the second he/she hit the like button.
