It would be a great feature to be honest but i'm not in a rush for this at all for now, it's something a was looking at and since a have the hardware to do it andthe rpi i'm working on right now has only two usb ports so adding an extra wifi interface would certainly be welcome in my case. I'll look at the source and see if I couldn't do something on my side to help you with this.

And please re-use the switches of N64
