He is as close to it as any mortal can achieve. The theories and ideas proposed in the book have been shown to apply and map to real life situations.* And while Eric Raymond makes good points in his analysis he is no Moses at the burning bush delivering gospel from way up high.
Lets take GCC, which is a C/C++/Java/... compiler (and what Linux/Mac/Some Windows users use to compile Warzone). It was a classic example of a Cathedral, hard to get code accepted, often behind closed doors and not really in the open. Sure what they did was good, but the developers were very clear about what they wanted and did not want. A lot of advanced users quickly grew tired of this and wanted a more open project, a free for all if you will.
So they forked, producing EGCS. The open development model (bazaar) soon showed its strength and after a couple of years was so much further on than the GCC project that it was 'renamed' and 'blessed' as the official version. I could go on (XFree86 & X.org is another good example), but I shalnt.
One could also argue that the same kind of thing has been shown in the real world, take the split from Rome by Henry VII. Now instead of having to go through the Catholic Church (Cathedral) to obtain enlightenment you could do it from the comforts of your bible and your soul.
This is the main problem with Cathedral development, as soon as you make a release there is a good chance that it will be forked as soon as it is released into the wild. The Cathedral attitude is one of the main problems which newly open-sourced projects face (normally from commercial code bases, or with commercial backing).
I agree there -- in the early stages of development keep things private can often allow for much higher productivity, however as a project gets larger the Skunk Works model just can not scale up, with the lack of red tape preventing evolution (while enhancing creation, however). Warzone is FOSS, and always will be, by the very fact it is released under the GNU GPL. There is no taking that away from it. (Hence why I have been using the terms Cathedral and Bazaar).In short FOSS can work for some groups & Skunk Works can work just as well for other groups.
As it stands in 2007 I am hard pushed to find an open source product that I use which I can not access the CVS/SVN repository of, that I can not chat to the developers of, and more importantly that I can not submit a patch to.
