Lived in an older neighborhood in Georgia a couple years back. A new neighborhood across the street had it (AT&T), but we didn't.

Caught an AT&T tech in the field one day, and he claimed that if 8 (or 10—memory's a little fuzzy) people in the neighborhood requested it, they'd bring it in.

I never did test it, but thought it interesting that they'd do it for that low a number. Of course, it may have been because it was already in the area.

Still, may be worth the ask for those who don't already have it.
