If you don't have cable or telephone based high speed service in your area yet I have seen a new higher-speed internet service being offered from one of the satellite dish providers recently. The service is not quite as high speed as the others, but it still is 20-25 times faster than dial-up service, and is available just about everywhere. The ad that I saw was from a company called Hughes, but both Direct TV and the Dish network have it too. Then you could take Alan's suggestion and try to share the internet service with a close neighbor too.
