Duh. Responding to my own post. But sometimes the mere act of writing
down the question helps one see the answer. It dawned on me that some
of the cheap but weak security methods, like the MAC based access list,
only prevent write access to my network. It takes some pretty strong
encryption to prevent read access. The signals are *broadcast* after
all.

I still don't really know what level of security is appropriate for a
home office network.
