During Oracle Open World 2010 (including JavaOne/Oracle Develop) a interview with John Bondi was recorded. John spoke about the Secure Global Desktop products history, present and future.
One interesting note:
Oracle and the SGD-product history together goes back to 2002, far before the Oracle-Sun merger and even before Sun bought the old Tarantella product.(The history of Everett and the SGD-product is of the same age :) )
