Locations with no good Internet (was ISP in Johannesburg)

From what I've read, they may well get higher bandwidth out to the town centers on fiber. There has been little discussion of how to distribute from there. I suppose Verizon, the only company offering anything out there, will take advantage and use the fiber to improve speeds in the centers of towns. But there's no CATV in most of the hill towns, and unless MBI intends to stretch fiber out to the neighborhoods, I remain skeptical.

Today, most of the town halls have public access wifi, and people drive up and sit in their cars and get their email that way. This isn't a solution.
