How many times will we all have to cry: "It's not the bandwidth cost, it's the charge for the damnable line!" Yeah, bandwidth charges are high, but they're the lesser evil.
There is only one solution to South Africa's telecommunications problems: first, remove all the monopoly-protecting restrictions and licensing requirements. Then, let anyone install international lines, be they satellite links, submarine cables or some kippie writing packets to disks and shipping them across the water. (Never underestimate the bandwidth of a truck full of disks!) Lastly, let anyone operate the "last mile."
At the moment, Telkom has exclusive control over all three! (Yes, even the legislation aspects: they have cronies, you know!)
