Don't get me wrong, I have done a lot of R&D on this and the main issues are uptime, speed, international speed, pings rates, interference, ICASA and distance, lastly cost. People are very unhappy with telkom (check out http://hellkom.co.za) and Sentech system now suck. On the PCFormat and PlanetMars forums I have found a lot of support for a good WISP which is our intention to setup. Our only problem at the moment is try to reduce the client side installation costs.
