DRBD merged into Linux kernel 2.6.33

The announcement doesn't state what DRBD is. It turns out that it is effectively RAID-1 running over the network. It looks fairly impressive and will make setting up mirrored servers easy as cake.<p>Personally though I'd like to see networked RAID-0 support in the kernel. It'd be neat just throwing a bunch of machines on a network and have them all act like a giant disk.

That's some impressive piece of software. I wonder if we are perceiving an acceleration on the rate of improvement for open source OSs. What other OSs have comparable technology?<p>And, more interesting, is it conceivable that FLOSS could be approaching a singularity?
