The latest post on the Adafruit Industries blog (http://www.adafruit.com/blog) features a video about using the WL-520gU to talk to Xbee modules for their Tweet-a-Watt project. My Wifi Radio tutorials helped them flash the router with OpenWrt and get everything working. They are using python on a memory stick to drive their data acquisition software. Pretty cool!
