Dropbox and the OS X Kernel

Damien DeVille:

Traditionally, Dropbox operated entirely in user space as a program just like any other on your machine. With Dropbox Infinite, we’re going deeper: into the kernel—the core of the operating system. With Project Infinite, Dropbox is evolving from a process that passively watches what happens on your local disk to one that actively plays a role in your filesystem. We have invested the better part of two years making all the pieces fit together seamlessly. This post is a glimpse into our journey.

Looks like I’ll be purchasing BitTorrent Sync after all.
