I've never tried the multiple SPI but I can suggest that most of the problems that I had with the WiFly have been related to the UART baud rate. In fact, I had it working perfect with the Netduino Plus with UART at 9600 but with the Netduino Plus 2 it needed to be at 115200. Without that speed I could send commands but it wouldn't respond. I'm also using the well developed code from Quiche31. Good luck.
