Since the thread has drifted to the virus question, I'll offer that Mickey$oft doesn't make AV software as such, but they do have a rather long list of people who do, at KB Article 49500.

Gareth might find his browser condom from one of those listed.

To the original subject of the thread - the article by Tim O'Reilly, I'll add the comment that O'Reilly Publishing is the last remaining publisher for whom I'll automatically assume that a book (1) will contain useful information, and (2) will contain the information described in the title.. His position, as founder of "O'Reilly" would give him considerable credibility; but the article stands on its own. It raises - and promotes - some very good points, and deserves to be read.

Note that at the article (linked in the 2d post here) the author's name is a link to information about some very interesting stuff - some of which I intend to pursue, and at the end of the article there is a link back to the "P2P Home" that also opens some interesting vistas.

Well worth exploring.
