There are a few projects in the KZN area which are offering a decently if not free priced gigabit speed for schools. If you pm me the school name and some basic details I can do a check for you.
That us why a rollout roadmap is needed as the area is not serviced yet. They are fully aware of the possibility of free fibre as well, and easily are the most prominent in getting donations and fundraising by their nature.
From a quick glance I was allowed they are with Bitco 50mbs.
