I've always wondered why some of the larger apartment complexes don't buy a fat pipe to the internet, and provide internet service to their residents (either as a perk, or a competitively priced service to make money). For example, the current complex I am in has hundreds of apartments - it seems like the perfect place for them to do so. Is it prohibitively difficult for them to find a fast enough pipe to the internet, or is there something else stopping them that I am missing?
