Useful sources on telecenter sustainability. The whole concept best summarized by Prof. Subbiah Arunachalam:
The success lies in embedding ICTs in a holistic approach encompassing a diverse range of development initiatives. The trick is not to emphasise technology but to put people and their needs before technology. Sustainable livelihood approaches need to be people-centred, recognising the capital assets of the poor and the influence of policies and institutions on their livelihood strategies.
