Arduino Wireless Shield

I'm looking at the new Arduino Wireless Shield http://arduino.cc/en/Main/ArduinoWirelessShield and wondering if it and the new official networking library will work with this XBee Wi-Fi module: http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/point-multipoint-rfmodules/xbee-wi-fi

Does anyone know if they would be compatible?

I have been looking for a similar shield on their site every week for the last two months. I see it is listed underhardware. According to the documentation, I would think it would support it. Though I too am awaiting official word on that.
