I expect a much-faster pace in that this should move in an exponential manner due to the viral nature of such technology. Moreover 'word of mouth' is going to greatly factor in as well. Huge market share and exposure is going to be possible right out of the gates. The technology platform can be used anywhere--this should be quite the SUPER-beta REAL $$$$ test with a huge initial entry into the African continent.
There are many humanitarian aspects as well which Ed mentioned (quite a few scoffed at this) MEC's solution should help to raise the standard of living and afford new economic opportunities for millions of Africans. In about 30 years half of the world population under age 35 will be living in Africa.
Can you imagine the positive effect for all invested stakeholders as such news and stories are disseminated to international news/business outlets?
