ABSTRACT
INTRODUCTION Re ecting in 1992 on the turbulent history of global communications, Arthur C. Clarke foresaw a world in which we have “reached the stage when virtually anything we want to do in the eld of communications is possible: the constraints are no longer technical, but economic, legal, or political” (p. 213). Developments 20 years thence inspire hope that some of those restraints are becoming more relaxed and that Clarke’s vision may indeed come true and thus make it easier for learners around the world to get unhindered access to learning opportunities.
