One of the things I have noticed in our house, parked as it is in the middle of suburbia, is the preponderance of wireless networks in our area.
Not only do we have good reception on our own wireless modem, we can see at least 4 others depending on where you are standing in the house.
This says something quite interesting about the extent to which networking hardware and fast broadband internet connections have become mainstream technologies.
The other thing that this has illustrated is that you can make technology simple and accessable, but as much as you spell it out in the installation instructions you can’t make make people take security seriously. Of those wireless networks I mentioned, only 2 had any form of security set up on them. The others were open for anyone to see/use/access/hack. I imagine that it simple constitutes ignorance on the part of the owners, but if they knew how much a person parked outside their house could access, I think they’d be pretty disturbed.
