In 2009 when South African IT communication was essentially only permitted through a single entity, as a publicity stunt a small ISP did an implementation of this:

As I recall at the time, the best consumer speeds available were 512kbps with a 3GB per month cap at today’s cost of about 45USD.

The worst part (especially as a WoW player) is that QoS was applied giving priority to ports 80, 443, 110 and 25. This resulted in all other ports having terrible latency, probably added 150ms on top of the unavoidable (due to speed of light) 190ms to get to European servers.

Fortunately today the situation is much better, there are numerous FNO companies and even more numerous ISPs for each.

I pay about 45 USD for an uncapped 100Mbps connection.
