C# XNA: AI Engine?

Question

I'm developing a game with a zombie running around in a swamp. I want AIs to have functionality like "chase this target" or "run away". A major stumbling block is a pathfinding. Is there a good pathfinding/AI engine in XNA, or should I roll my own?

Does anyone have any experience with this: http://www.codeplex.com/simpleAI?
