Kappadev,
First off.. brilliant, eh? That's something we don't hear often enough! Thanks!
We're currently in the process of evaluating a few different changes. They may do what you're looking for, as well as some other things. It's pretty easy to do too. Please go to your Facebook Application settings area, below:
developers.facebook.com/apps/
Click the "Edit Settings" button and then in the "App on Facebook" section, remove your URLs from the "Secure Canvas URL" and "Canvas URL" settings. Hit save.
That should remove the extra stuff from the Like button that you don't like.
Please let us know how that goes. We're looking into updating Autotune to not automatically set those values, as it does right now, as well.
Best of luck, and thanks,
Alex
