FFS, it's like you whippersnappers have never heard of rsync or makefiles. Dropbox requires the mouse, and therefore means that you should get off my lawn.
Seriously though, a Makefile in your web directory with a default target that rsyncs your content up to your webserver via ssh solves this problem much more elegantly, without relying on a third party service. Bonus points for you if you render/minify your sass/scss and/or coffeescript as a target dependency.
PS: Put your remote username and remote port (if custom) for a given host in your ~/.ssh/config file, along with any necessary 'ProxyCommand's to allow direct "rsync ./ $hostname:public_html/" or such in your makefile.
