	I'm not trying to fix the underlying wireless encryption
option just provide a simple way that the manufacturers can ship
a 'more secure' out-of-the-box-product.

	Absolutely.

	There are a lot of things one can do:

	1) enable wep
	2) rotate wep keys
	3) authenticate by mac-address
	4) restrict dhcp to known mac-addresses
	5) force utilization of vpn/ipsec client

	Obviously not all of these solutions are available
in all cases, but in a home or small lan-environment a subset of
these will increase security (even if it's reinforcing the screen door
with 1/16" of balsa wood)

	- jared
