True it may not be worth it, but if you say live in a townhouse and there
are several people around you then, maybe it is worth it to sit there and
pick up say 4 peoples identities for 1 hours worth of work. And if these
are well todo people you could have access to some nice credit lines, and
This is just in theory, and may not be a big thing now, but it is
definitely something to keep in mind in the future. And of course this
scenario won't apply to everyone.

I have found that spaghetti tastes better with tomato sauce instead of

I would love to know of some cheap wireless repeaters my self. Suppose you
could do it with an old Linux laptop with two wifi cards in it (one acting
as an access point one acting as a client from the other access point), but
that wouldn't be as efficient as I would like. Besides that, you could
build an add-on antenna for your base station to try and increase your
"vulnerability" ( ;-) ) further into your backyard.
