Computing in Rwanda?

gehel asks: "In September I will be going to Rwanda, working for a year in a developement project as a Computer Science guy. I'm leaving with an association that doesn't have much experience in sending CS guys over there, but I'm sure some Slashdot readers have some experience in that field. For all those who know Rwanda or Africa better than me, or for those who have been working in developement projects: What should I be prepared for? What would you bring with you to go there? How do you think we can bring Computer Science to a developement project in Africa, without creating too much dependencies on the North? What are the typical failures of such projects?" "I don't know much about what I am going to do there except : I will be based in Kigali. I will be working (at least partly) as a sysadmin with existing computer installations (most probably Windows based), I will do some teaching (mostly in system administration), and I might work a bit to help creating a new radio station. Finally, I'd like to add that I am proud to be doing this as a service for my country."
