So I am not sure exactly what the deal is, or how this works for that matter but when I used the Kismac AP scanner software quite a few new networks showed up at home. I usually only see Zion, which is my Airport (yes I like the Matrix). Standing in exactly the same place in my living room I was able to see four additional networks. I can sometimes see additional networks walking around and trying placements near my ceiling or floor, but this is amazing. Kismac uses its own drivers instead of the standard Airport driver which is clearly enhancing the range and signal on my PowerBook.
