You'd be lucky to use WiFi on a rather low-tech neighborhood, as folks around you won't have the tech savvy to sniff your network data or take advantage of your WiFi access. Some
WiFi users secure their networks by preventing it to get advertised, and sure this is one of the best ways. It's still very experimental though, and quite difficult to configure. The best way to find WiFi help over security is to check out the forums each time, in case someone has a particularly bright idea.
