The closest that DFA will bring fibre to our houses is FTTC - fibre to the curb, e.g. to the boundary of gated complexes.
What has happened elsewhere, like The Netherlands, is that the encumbent (kpn) forms a joint venture with another company. kpn provide the fibre to an Optical Distribution Frame that is owned by the JV. Everything from the ODF to the customer is then supplied and owned by the JV.
This model is possible in selected areas in South Africa, as Telkom already has ODFs all over the place (UMCs, etc). Currently there is copper from the UMC to the customers.
By installing an ODF at the UMC, we can very quickly roll out FttC and FttH. Because of the shorter distances, the fibre can be carried on the existing overhead network (poles) and does not have to be buried in pipes/ducts.
The JV will then be responsible to maintain the network from the ODF to the customer, either by doing it themself or outsourcing it to a third party.
