543781 Facebook like jacking

So i want a script which will make every user who visits my site first click to like my facebook fan page without even knowing it. After that first click this script needs to disappear. This means invisible like button will need to follow the cursor everywhere on the screen. I want this additional options as well: - Script needs to check if a visitor has Facebook session cookie and if he doesn't,script should avoid him so that he doesn't get facebook login popup - If user successfully clicks like button he should get lifetime cookie so that next time he visits my site script avoids him - Script needs to work in all browsers
