Online Education on the Horizon

Online learning is one of my main concerns today. I'm actively working in understanding what online instructional models are the good ones for different kinds of students: university, residents at hospitals, professionals improving their knowledge, etc.
I've been looking at different (and innovative) e-libraries, e-books, e-book readers, online databases and other content containers but a single one made me completely happy. 
I'm also following in Twitter different specialists and people interested, like me, in e-learning and the future of education. It seems to me that all of us are disappointed by the lack of real innovation in this field.
Most of the key opinion leaders expressing their ideas on the net seem to end in the same concept: The Future Doesn't Fit in the Containers of the Past (Rishad Tobaccowala, CEO Denuo).
We have an inmense opportunity to innovate and try to find the correct models for e-learning.
