But not more so than networking over the household wiring. I just can't
conceive of a way that a network _designed_ to be broadcast can be more
secure than a hardware network using the same encryption methods.

Run DC in the wires :-)

I don't get it - what's the value of removing an antenna? In fact, they
transmit _and_ receive on both antennas. The antenna with the better signal
gets used, which works beautifully on my router - configured as a WDS
repeater, one antenna connected to a dish pointed at a router 1000' away,
and the other using the original stubby. The machines in my home
communicate via the stubby, and the two routers communicate via the dish.
