PSvita is an amazing mobile playstation, specially with the remote control feature except that the R2, R3, L2 and L3 are very not easy to use. That's why I developed this PSVita Grip which is able to fix the DS4 and the PSvita together. Now, it's possible to play at your favorite PS4 games on your PSVita with your DS4. (There are some tutorial on the internet which explain how use your DS4 during remote control). Update (20Nov14) : Added a hole for the audio jack.
