I tried to order it and it looks like they go off the billing address of you credit card. I have a Dallas address and was denied. It is theoretically possible that they could find your geographic location form your ip address but I doubt they go through the trouble. By limiting it to people with Louisiana billing address they show that they are doing their due diligence to enforce the black out. Although this is only my opinion.
This is Freakin' AMERICA! What has this country come to??? What harm am I doing if I get it sitting in my living room 150 miles from the Louisiana border? I still don't understand why I have to live there to buy an internet feed! Does anyone know? It's not like state tax dollars are paying for it. Could it be a way of limiting the number of viewers? Might they need to do that because having too many people on the site would mess up the quality or something? What gives??????????????????????????????????????
It's very simple to find out where you are through the whois records of your ISP. not a problem at all, plenty of online web services exist to do that.
It's not necessarily that easy. For example: If I were to access the internet from my office, the IP address would show up as being from Tampa when in fact I would be sitting in Dallas. It's because our corporate internet gateway is in Florida. Physical location and logical location are not necessarily correlated. They would have to use some type of automated whois check because there is no way they do it on an individual basis. That would work in most cases but what about the legitimate exceptions?
