Is Panda II compatible with the WiFly Shield?
It will work but will be a bit slow. Sparkfun shield uses a SPI to UART bridge because arduino only has one serial port. Panda has 4 serial ports and it is best if WiFly is connected to a UART directly.
Another option is to use XBee-formfactor wifly with xbee shield so you are using UART. Or best, just get a breakout with wifi and wire it to one of the UARTs.
Speaking of wifly, have you seen this? http://www.tinyclr.com/forum/topic?id=8680
Thanks for the replay. Yes, I saw that link (http://www.tinyclr.com/forum/topic?id=8680).
If I understand correctly, FEZ Cerbuino Bee need for WiFi only XBee Module (http://www.phenoptix.com/index.php/adafruit-xbee-module-wireless-communications-for-arduino-1mw-1-mile-radius.html) and that work without one problem.
You need wifi module. Please see this http://www.tinyclr.com/forum/topic?id=8680
