global warming

What walls don't come down in this hour-long talk? Bye-bye edu-caste system, bye-bye geographic and temporal barriers. My guests are from three continents and four levels of school hierarchy:

* High School Principal Noel Thomas, Toorak College, Melbourne, Australia
* High School Principal (and next year's Director) Rich Boerner, Korea International School, Seoul, South Korea (my former employer)
* Librarian Jenny Luca, Toorak College, Melbourne
* Lara H., high school student, Toorak College
* Lindsea Kemp-Wilber, Punahou High School student (and Students 2.0 staff writer), Honolulu, Hawaii, USA
* and me, high school teacher and tool-guy, formerly of Korea International School
