Free Public Wifi!

Finally, an explanation for why I keep seeing "Free Public Wifi" in more and more places.

...Windows XP and friends are designed to pretend to be certain kinds of WiFi networks that you might have connected to in the past (a so-called AdHoc or peer-to-peer WiFi network). AdHoc networks aren't that common, but the point is that if you ever tried to connect to one with your WinXP laptop, later on it will broadcast to the world that it is that network.

Then other laptops will see that network, and some will try to connect, and they are then "infected" with this broadcasting "virus." It's not a traditional computer virus of course, just a set of behaviors that spread virally. The most widely spread early names will continue to spread even more because of the nature of this system. Ever see a network called "Free Public WiFi" but when you connect, it didn't work? Congratulations, you are now part of the problem....
