Wish I had found that article before I posted the question. Thanks for sharing it. But then, if I had found that article -- I wouldn't have needed to 'ask slashdot', would I?
Unfortunately, while the article you reference refers to a whitepaper and a presentation made by Scott McNealy, those materials are not published anywhere that I could find. If you know where they are -- please tell.
The need for a federal CIO is certainly a good part of the discussion, too. That there is not a federal CIO is very strange indeed. It sounds as though Scott did get his chance to make the pitch for using OSS to build vendor neutral enterprise environments. I hope that message doesn't get drowned out by the lobbyists.
