I recently had a Windows-7-commercial-esque epiphany: What if Apple implemented the double-tap 'gesture' on the homescreen or even universally? Note: this was a bit of a on-the-fence epiphany. I'm not exactly sure how this all racks up with the pros and cons.
How could this be implemented? Or would it just not work?

there are some double-tap gestures, such as double-tap to zoom. If it was OS wide and used on icons, it would detect the speed of your tap and you'd have to tap twice quickly.
