Box.net, a popular online storage service, added an alternative that allows its users to create and edit documents and spreadsheets by Google Docs, but without leaving Box.net. The files are stored by Box.net, but they can be shortened using the regular Google Docs interface.
"Beginning today, Box's 6 million users can simply create and work together on Google Docs and Spreadsheets from within Box, as well as edit the existing 50M+ Word and Excel files previously stored on our platform. Google Docs allow entirely new forms of collaboration – like concurrent editing – that are not possible within desktop applications, and now these capabilities are easily obtainable to Box users. We believe that the mixture of Google Docs' collaborative restriction and Box's content management will transform the way people work," suggests Box's blog.
The addition has a lot of quirks: Google Docs still displays the navigational bar and some options that only makes intelligence for Google's services. When you edit a text from Box.net, the file is provisionally added to the Google Docs list, but it's quickly removed after the restriction window is closed. At some point, Google Docs will also add hold up for third-party apps, so it will be interesting to see if this feature will be better implemented.
