I think African involvement is even more exciting than most countries, due to the draconian systems they have in place in different regions. This could be the start of something really big.
Actually, when it comes to mobile payment technologies, Africa is one of the most advanced (if not most advanced) continent in the world.
Seriously, in Africa you can already pay for everything with mobiles paying small fees - like nowhere else in the world.
I think that there are great possibilities for Bitcoin not only through mobiles, but also embedded & low power devices, because many africans have access to very little amount of electric power (YET they still have mobile phones - unbelievable, isn't it ?).
