Naspers via Media24? The guys I've spoken to there are smart. If it is then they would be able to offer you a lot of resources that would be very difficult to otherwise get hold of, especially in SA. Unless you really feel its going to fly (in which case it would probably be better to try get financing via equity with no exclusive partnerships) I think that partnering with a company such as one per your description would be a good way to position it for growth - particularly if you are not keen to move from part-time to "full-on startup mode". The points by westside1506 and esessoms are both very valid - worth bearing in mind. Geluk!
