This has been a thing for a while; I remember using it (or something like it) several years ago. While it's great for random files you might want to place in the G-Cloud, what I really wanted was to access my google docs content from the Linux command line. And you can do that, it's just that they're in non-obvious, non-documented, frequently changing formats that will only ever be usable with Google Docs.

But if you're using the google cloud like you might use Box.Net or DropBox, it seems fine for light usage.
