Kiva.org
I am slightly reticent to publicise this at the moment given that the BBC just has. But Kiva allows people to lend money to a specific cause in the developing world.
You can choose your cause from a list and, when the money is repaid by the donee, it can be redirected towards other good causes. Unlike charitable giving there are no expenses taken by Kiva and you can choose causes that you believe will help the country in question to progress.
