There are several options out there. The one tony has is using 802.11(i think). The ISP has a directional antenna pointed at tony's house and tony has a directional antenna on his roof to recieve the signal. Tony probably has another antenna pointed in the other direction to repeat the signal on down the valley. It sounds like the guy built his own router which does the bridging and routing. The WAP 11 can do this too, but its 150-170 dollars. Im fairly sure the signal wouldnt carry too far without the directional antenna. (Maybe a few houses down) There are other hardware alternatives available for this sort of thing including nokia rooftop (http://www.wbs.nokia.com/solution/index.html) and a cool non line of sight solution from navini networks.
