Wireless devices also have access to random processes unique to the wireless medium. Things like or RSSI, or perhaps some other low level radio related parameters related to fading probably generate a fair amount of entropy. Would that be usable? Use of WPA would go hand in hand with using the wireless interface.. thus generating randomness. ;-) - aidan
