Since it seems to be based on Google Documents, I think Dropbox will do just fine. There are few pages on the internet that I dislike more than the Google Documents start page. I actually feel annoyed every time I look at that auto generated shit list of files that is Google documents. It breaks every user interface convention for displaying a list of files. Navigating files is something I already know how to do, but Google is special and has figured out how to make it a chore.
