Comcast in our area was willing to run the line to an office if we paid for the cost of running the line. At the time they needed a new distribution hub with it so the cost was $60k+. 2 years later they changed their tune and did it for free in return for a 2 or 3 year business class internet contract.
Chances are good you'd need a hub in your subdivision so it isn't like running a single cable and daisychaining the houses will work. If you can get commitments from enough of the neighbors however, you may be able to get somewhere with the company. 10 homes wanting $100/mo cable+internet adds up to $1200/mo and $14,400/yr. That might get them interested. 5 of you wanting $40/mo Internet only isn't likely to get them interested.
