- Description: It is increasingly being recognized that faster socioeconomic develop-ment in Africa is dependent upon the development of Information and Communication Technology (ICT) Infrastructure for the dissemination of data and educational services. The scalability and flexibility provided by Cloud services in terms of resource management, service provisioning and virtualization makes it an attractive system for use with educational and ICT services. The flexibility of pay-as-you-go models combined with the ability to scale computing, storage and/or networking resources makes Cloud computing an ideal candidate for use with education, re-search and scientific infrastructures. Notwithstanding its benefits, transi-tioning from a traditional IT infrastructure to a Cloud computing para-digm raises security concerns with respect to data storage, data trans-mission and user privacy. This paper presents on-going research for the development of Science, Technology and Innovation (STI) infra-structure for the distribution of Information Communication technologies (ICT) services in the African context. The Inter-Cloud Infrastructure Framework (ICIF) proposed, is conceived as a Cloud computing framework suitable for use with National Research and Education Net-works (NRENs) in the SADC region. The ICIF system is used to create an Inter-Cloud infrastructure, and helps NRENs transition from tradi-tional IT infrastructure systems to the Cloud computing paradigm. It also provides new functional/operational components and Cloud services to support the interconnection and/or interoperability among SADC NRENs through the ICIF infrastructure.

- Description: There has been much attention recently on the use of virtual class-rooms to support distance learning. However, the required real-time and high-rate transfers for multimedia contents such as video and audio that comprise most off-the-shelf virtual classrooms make them infeasible for developing countries where bandwidth is typically more restricted. This paper describes the findings of an ongoing investigation to develop a low bandwidth virtual classroom that can provide the necessary func-tionality to deliver courses to distant students. By combining Google Docs and Skype, we realised a low bandwidth virtual classroom alterna-tive that could provide adequate functionality within our teaching con-text.

- Description: The SANTED Virtual Classroom Project is a collaboration initiative of the Departments of Computer Science at Rhodes University and the University of Namibia, conceptualized in 2007 and operational since 2008. The project aims to build capacity in the Computer Science De-partment at the University of Namibia through curriculum development and delivery, staff development and sharing of resources. This paper gives a detailed description of the project, highlighting how it was con-ceived, its aims and objectives, its aspirations and challenges, as well as some of the successes achieved to date.
