Default Android > Android Remote kb/mouse/control app. Does one exist?

I'm trying to use my broken screen'ed Nexus 4 as a XBMC unit. Trouble is, its a bit of a pain to do anything on it because of the screen being broken (touch screen 25% of the area works).
So basically I need some software which allows me to connect from a "client" (ie other phone/tab) to control it. I know i can use Yatse or any of the other XBMC remotes once i'm running XBMC but there are times where i need to do other stuff on it.
Anyone have any ideas? I've tried Tablet remote which does some of the things. But it only really has functionality of a keyboard arrow keys ther than touch/mouse control. Also I know there is another app which seems pretty useful but it has been open sourced called Screen Standby which apparently has a remote control aspect but since its a pay for app that hasn't been updated for nearly a year i'm reluctant to purchase.
anyway. thanks in advance.
