The service can also be used to track people. Besides that, it should be obvious that this service can be provided by your neighbors without BT cashing in. In fact, full Internet access can be provided for free in the entire city, and the entire country. If you walk through London, you will notice that it is hard to find a spot *without* wifi access. The vast majority of wifi access points belongs to your friendly neighbors. All it takes to treat the Internet like a public road system is to replace BT with a public backbone service. The backbone is already heavily subsidise by the tax payers. Suddenly there is a free infrastructure available for everybody. Yesterday Comcast, today BT - I think the ISPs are scared witless (or wireless?).
