Realizing that this thread is several years old, I still believe that the topic is highly interesting & relevant, that's why I'll try to re-vive it.
I am currently working on a research on penetration and usage patterns of Open Source LMS in Higher Education in Southern Africa, and I would be very happy to get in touch with basically anbody who relates to that subject. The region I am particularly focussing on (due to the restriction I had to indicate in my research proposal) includes Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia and Zimbabwe - but of course I am more than interested in an exchange with people from other parts of Africa too.
I'd be very happy to hear from you, you can also get in touch with me via email@example.com
Cheers from Austria!
