Virtual Joystick for Windows Phone 7 (XNA)

Question

In the iOS space, there's a great library based on Cocos2D called SneakyInput to create a virtual Joystick on screen. I was just wondering if there's a (preferably free) library like that for XNA? If not, are there any resources someone can point me to on how to roll my own? It doesn't sound overly complicated, but when I think something "shouldn't be that difficult" I'm usually overlooking smaller details.
