Maybe you guys already know about this but looks like the drivers for WiFly are already in this toolkit
http://netmftoolbox.codeplex.com/wikipage?title=Toolbox.NETMF.Hardware.WiFlyGSX&referringTitle=Supported%20devices
Those Roving Networks modules are found at sparkfun, http://www.sparkfun.com/products/10822
This makes adding WiFi to cerbuino, cerberus, hydra an easier options. I think someone in the community was working on this support so this maybe what you need or a good start.
