The closer you are to the Internet, the more powerful open source becomes.
That's the lesson of this, a Burton Group report that the open source JBoss application server is now in a virtual tie for first in that market with IBM's WebSphere.
Whether or not JBoss is first or second is not as important as the fact that it's highly competitive. It's a viable option in this vital enterprise space. And when you look at the rest of the list, what you see are an evolving, changing set of business models. BEA, Sun, Oracle and Novell are all playes in this game.
Open source, as opposed to the GPL,. is an evolutionary process. Companies can set their business models anywhere they wish along the continuuum, and can adjust as they evolve. I personally believe this evolution moves toward the GPL. It's the model that brings the greatest open source benefits, if by benefit you mean help from the community.
But let it play out.
And before we go with the obvious picture of the dinosaur and the snarky "it's the proprietary model that is extinct," remember that avian dinosaurs, or birds, apparently survived the asteroid, and live among us still. There's a lesson there, too.
