How might the outcome of the boer war affect other africans? how did the outcome affect britain's reputation as a superpower?

The boer war, if it happens (hopefully not), will have devastating consequences, first for RSA itself (Swaziland and Lesotho in package with it) where there will be lot of casualties and the economy will go down significantly, then an even bigger problem on a bigger scale may emerge because the treatment towards white people in Africa in multiple countries is on a primitive level, so a chain reaction is almost certain, which can push big portion of the continent into war if and when the world power houses intervene.
Britain's reputation as a world superpower will be affected positively if it prevents the war and impose themselves as a big factor that should be feared and thus calm down the tensions, or negatively if it allows a war to break down.
