Digi's WiFi XBee

I know that this is a pretty new product but I'm wondering if anyone has had success interfacing it with an Arduino. I received the basic dev kit and ran through the basic "getting started" exercises OK. But I'm really lost on where to begin as far as interfacing it with an Arduino (in my case a Mega). There's very little documentation on Digi's site but it looks like it might be interfaced similarly to their Zigbee modules (which have a lot of documentation and code samples).
