T1 + Wireless here in Santa Fe (Score 1)

I agree with the folks suggesting T1 + wireless for neighbors. A very successful service here in Santa Fe is La Canada wireless, which as earlier folks mention, share a T1 with very simple 802.11 wireless, building a very effective network for those unable to get a cable modem or DSL. Indeed, they would not now change, even if cable/DSL did become available.
