Lewis Carroll and Virtualization.

"Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, 'and what is the use of a book,' thought Alice 'without pictures or conversations?'"

               - from her Wonderland in 1865.

And so... What is the use of a classroom, without a whiteboard or collaboration?
