Remote for itunes library on iPad, controlled on iPhone?

Since I'm using my iPad as my musiclibrary (no need to power up the mac for a little music), connected to my stereo via Airplay, I'd really like to be able to Remotecontrol the musiclibrary on the iPad from my iPhone, just like Apple's "Remote" app can remotecontrol iTunes on my Mac..

Is there an app for this?

If no - why not? I don't actually wander around with my iPad in my pocket...

..anyone?

I would think i'm not the only one playing music from my iPad..?

Thanks man, that seems to do the trick!
