I did this about 18 months ago, and surprisingly, Spectrum came out and actually put a new line up my road. I'd asked them off and on for years to get broadband. Last time I'd been quoted 12k to cross the little creek they stopped at and service the dozen or so houses on my side. But for whatever reason, this time they did it for free (well, normal hookup costs) after I challenged them on the FCC site.
