I personally spent the past three years traveling to and communicating with CCIEs, Network Academy and Cisco Channel partners in these regions. It is my experience that there is a demand but in most cases once a gifted network engineer achieves CCIE certification they exit the country. There are places in Africa cash heavy and technology light so good engineers have been getting fair wages to move within the continent. Yesterday I saw my first req. for 2011 from South Africa. While hiring was sporadic in Angola, Kenya and Nigeria for me personally, I did see the activity going on thru other sources.
If I could get more CCIEs visas I would believe me because I have met some very gifted technically astute IEs there.
