Android to Android control

I recently read (though I can't remember where) that it's possible for an Android Tablet to be controlled by an Android phone using Pocket cloud.
I've given it a go using droid vnc on the tablet and using the Mac setting (as advised in the article I saw) to connect on the phone and I can see the "desktop" of the tablet on my phone and it looks great.
However thats all I can do, the touch pointer moves but doesn't have any effect when clicking an app or control.
I was hoping that I could use my tablet for music and videos output to my TV via HDMI, and using my phone to control it, can Pocketcloud be used to control one Android device with another?
