I'm certainly no expert, but I think the point is that wireless
networks are like radios - they broadcast their content without
regard to any listeners. While my laptop may not be permitted to
participate in the network itself, it isn't prevented from listening
merely by MAC address controls on the router. I can sniff the
packets "out of thin air" and determine the MAC address or addresses
that *are* allowed to participate in the network, and then alter my
MAC address to one of those.
