Best Remote App?

Looking for suggestions for a remote app to mimic the functionality of a wireless keyboard and Magic Trackpad. I'm picturing a super light, unbloated app that makes my idevice a plain Magic Trackpad with a button to pop up the keyboard.

For the computer I have a rMBP 15" (10.8.2) with an external monitor. It may be relevant to note that I use BTT (and naturally, I want to retain that functionality, as you expect with a wireless keyboard and Magic Trackpad), and my idevices are jailbroken so I'm comfortable using a polished jailbreak app.
