Virtual learning seems to progress, as I have suggested numbers of times, and to which I actively try to contribute. An interesting thesis is made, comparing different typologies of educational sites. It gives an nice state of the art.
Furthermore, the European Union announces a pilot project that prepares for a "Virtual Erasmus": a European project for virtual mobility of students. Though it only concerns a pilot for the moment, the project seems promising and could open entirely new ways of (continuous) learning.
Yet another interesting source, going in the same direction, is a kind of a virtual library. If you would like to see its potential, just try to search on "complexity".
