Using the one computer classroom for global communication

As I reflect on the article 6 Ways to Turn Your 1-Computer Classroom Into a Global Communication Center,  I note that in the Caribbean context, the one computer classroom is used mainly to support content area teaching rather than for purposes such as social networking. Although there is limited used of  VOIP  and messaging connections in the teaching and learning process,the computer is not a main tool to bring experts and other resource persons  from outside into the classroom.
