It's pretty easy to setup box.net with webdav and to have your files automatically saved to box.net. I got 50gb of storage space on box.net when I bought an HP Touchpad 32gb on firesale.
However, because it's not a paid or professional account, I can't really do anything with it.
UPDATE: I don't use this setup because box.net is just too slow and some people have been complaining that they don't implement webdav properly. I really wish they'd come up with a client for Linux like Dropbox has.

Sorry, no comments enabled for now because I'm using a simple static site generator (maybe I'll try out disqus another day).
But if you like what you see, send me an email.
