I was wondering if there was any thought to shielding and/or guiding
the wireless signal, to 'aim' it so to speak and thereby preventing
(at least the majority) of it from broadcasting all over the place.

Of course the main line of security is encryption and password
protection. But I was also wondering about setting up something I'll
call 'shadow' to cut out whole regions that don't need any coverage in.

An example; a home user places a wireless router in the corner of the
room near the phone jack. Since the wireless node is sitting up against
two walls why not block/reflect the signals coming from it back towards
the rest of the property, perhaps in some way gaining the benefit of
increasing security against roving folks who might seek to tap your
signal.

Besides the seemingly paranoid aspect there might also be some improved
reception to be had from concentrating, focusing if you will a directed
signal _towards_ the intended recipient in the dwelling. Even if it's
intended for a roving laptop the coverage doesn't need to be a full 360
degree bubble around the wireless hub.

Perhaps it might be something simple as sitting a stainless steel bowl
or mirror behind the hub, perhaps it might really require some
engineering.

Just a thought tossed out to see what discussion might come from it.
