[Skunkworks] SA cell phone law- good or bad thing?

As of the 1st of this month anybody buying a pre-paid line in South Africa will have to provide proof of address- even tourists buying one for the short stay. Existing subscribers will have to register too or risk disconnection but the deadline has not been set. They say it's to control organised crime and now your phone can be tapped if a court order is given. Opinion is divided but is this a good or bad thing? On the outside they look justified but it's can lead to invation of privacy. One of the selling points of prepaid is ease of connection and annonymity. Any plans for the same in Kenya, Maoni?
