I'd put more money on enough people finally paying enough attention to DragonFlyBSD for it to really gain traction. Check out the blurb on their main page (http://www.dragonflybsd.org/ http://www.dragonflybsd.org/): The DragonFly project's ultimate goal is to provide native clustering support in the kernel. This involves the creation of a sophisticated cache management framework for filesystem namespaces, file spaces, and VM spaces, which allows heavily interactive programs to run across multiple machines with cache coherency fully guaranteed in all respects. This also involves being able to chop up resources, including the cpu by way of a controlled VM context, for safe assignment to unsecured third-party clusters over the internet (though the security of such clusters itself might be in doubt, the first and most important thing is for systems donating resources to not be made vulnerable through their donation). If anyone truly "gets" cloud computing, it's these guys. And they have the advantage of not being quite as big of a jump from existing systems as Plan 9 is.

I don't know, they'vr got some coverage with HAMMER a couple of years ago, but where did it lead them?

with cache coherency fully guaranteed in all respects It's not at all clear that this is desirable. I'd much rather have thin (one or two socket) systems with a reliable network and write for distributed memory. Even four-socket systems have quite unpredictable performance characteristics.

> which allows heavily interactive programs to run across multiple machines with cache coherency fully guaranteed in all respects. Cache coherency gets increasingly expensive with scale. At some point, the costs exceed the benefits. The location of point depends on lots of things, but if you're on the other side.... Also, there are many kinds of coherency.
