EDUCAUSE recently released a book entitled The Tower and The Cloud that addresses some of the promises and pitfalls presented by resources that exist 'in the cloud'.
Richard Katz, the book's editor and Educause VP, indicates that the book is “a celebration of what is possible and what is becoming possible,” but also “a cautionary tale.” further adding that “...we don’t know really what happens when you make your infrastructure interdependent with Amazon or you place your data in the care of Google”
They are clearly walking the walk with OER as the entire book is available as a PDF from their site.
