It would be interesting to actually read an analysis with say tables/graphs of when things were promised and when they were actually implemented - sort of timeline. E.g. in 1995/6 the SNO were promised to be operational by 2001/2, but only becoming operational in 2006/7; ADSL regulations in effect in 2006, but Telkom et al not yet abiding by the law, etc. It shold be done across the whole sector, i.e. not just govt but Neotel, Goal, MTN, Vodacom, iBurst, etc. It would provide a factual basis from which to critisize companies actions and try to interpret any new promises, such as Infraco becoming operational and reducing prices, LLU, etc.
If the research is too much for one person (given time constraints) maybe a wiki type entry would do and make it an ongoing research project.
