This feature is now available and you can actually get it on your Nexus phone by using an awesome TouchControl app!
+Bartosz Ponurkiewicz, known as bponury, the creator of awesome hacking and spoofing apps like Faceniff or Wifikill, has also created the TouchControl app - an awesome, useful, yet very simple app letting you to take control over your phone's screen while it's off.

You can enable the screen by various gestures:

              • Slide2wake (slide the finger to wake your phone up)
              • Slide2lock (lock your device by sliding your finger)
              • Slide2media_next (skips song by sliding)
              • touch2wake (wakes the screen by touching)
              • doubletap2wake ("knock knock" G2's feature)

The app is currently available for Nexus 4, Nexus 5, Galaxy Nexus and Nexus 7 (2013). It also works only with custom kernel supporting this feature (check here).
