I was reading an article on wordpress using dropbox to keep the theme files:

I am also seeing articles to use Google appengine as a CDN:

Can we do the same for flatpress?
Also, is there a way to backup and restore (using a plugin) the flatpress site directly to/from dropbox or other free altrenative sites?
There are a lot of plugins in wordpress for this:
