Ok so once again browsing the interwebs and I stumble upon another kool free program. The one this time is called inSSIDer. It will basicly take all the wifi networks and put them in a list for you. And then it will graph the signal strength. I can think of some fun wardriving applications to pair this with! I have tested it out on the eeepc and it seems to work decently so if you are looking for a program such as this then I suggest taking a look
