As Tony described it, we encountered "some bandwidth problems" during the e/merge 2006 opening event. Kuzvinetsa Peter Dzvimbo, Rector of the African Virtual University was unable to present his keynote speech live because of poor connectivity between the AVU's Nairobi offices and the Breeze Server at the University of Cape Town.
We have had similar problems in tests from the Ministry of Science of Technology in Mozambique, and thus are converting a 2nd possible live presentation from Venancio Massingue, Mozambican Minister of Science and Technology, into a pre-recorded slideshow.
Sad to say, the bandwidth required for this sort of audio conferencing (with a little video) is not much - Breeze has a range of bandwidth options starting from around 25 Kbps. Nevertheless, somehow reliable end-to-end connections that can sustain uninterrupted live audio seem to be hard to come by in Africa.
So it's ironic that in an online conference about e-learning in Africa, it's easier for us to present live sessions from presenters in the US, Canada, Netherlands and Hong Kong than it is to hear African voices from neighbouring countries.
So here's to everyone in Africa working on improving regional Internet connectivity and peering, lowering bandwidth costs and overturning telecommunications monopolies. It can't happen soon enough. Bring on the African telecomms renaissance.
