Please check out ColaLife and the work they are doing by trying to leverage Coke's transport system in Africa to deliver medicine.

ColaLife is a campaign to get Coca-Cola to open up its distribution channels in developing countries to save lives, especially children’s lives, by carrying much needed ’social products’ such as oral rehydration salts and high-dose vitamin A tablets. For the latest on the campaign. ColaLife is an independent and purely voluntary movement backed by thousands of supporters on its Facebook Group. www.colalife.org

Here is a great video on what they are trying to do.
