Not a Sublime user, but you can do this with many (most?) apps with simlinks from Dropbox folders into the "~/Library/Application Support" folders of your various OS X devices.
Some apps won't enjoy being open simultaneously, but if you keep this in-mind, this is generally a great solution.
Therefore Dropbox, not a homegrown process, syncs your settings
