Even being a company that spends 50k a year gets you next to nothing wrt feature requests or support outside of what would be given to a free user, aside from speed of reply. If you want any level of control over data and sharing, you're sent over to "sookasa", a shambles of a business, or you can look at non-recommended solutions like boxcryptor (an incredible product that unfortunately carries it's own administrative overhead).
If anyone from Dropbox is reading this, the things that make my life the hardest are:
1) removing shared folders from a user's account. (Impossible unless your IT department controls every shared folder in your organization. Difficult & time consuming if they do)
2) Deleting a corporate account from all devices, removing folders. (Impossible)
3) Offering any sort of encryption (need to use 3rd party, unreliable)
4) Managing/reverting changes. Terribly ugly, difficult, and time consuming process. It's bafflingly inefficient, and in an organization of any size clueless or new hires are going to create these problems on a weekly basis.
5) Management and reporting APIs don't exist.
We don't do any of the things you list - not even close - and we don't ever plan to.
We can, however, do this:
pg_dump -U postgres db | ssh email@example.com "dd of=db_dump"
ssh firstname.lastname@example.org s3cmd get s3://rsynctest/mscdex.exe
1) Not only do we let you remove shared folders from a user's account, I designed our remote wipe feature that can go and delete those files from users computers. (It's a best-effort approach.)
2) We also support remote wipe from devices as well.
3) I'm not sure what kind of encryption you're looking for. In general, encryption with cloud storage introduces support difficulties, and makes it hard to do web-based access. We allow you to host your files on your own servers, so that might provide enough security to address your concerns.
4) We do allow reverting a folder to a known date, but you need to contact support.
5) Unfortunately, our APIs aren't public. Our management tools are in use at many large organizations, though.
Dropbox will keep me as a customer purely because my entire business is run on Linux (except for the Mac my business partner uses).
It's interesting to see the changes in the market since when Dropbox pioneered it around 2007 or so.
I think all your points are very solid. I would, however, disagree with you about Dropbox or any other cloud provider implementing their own, in-house, encryption.
They're the one with the data and having the key to open your data as well is, to me, a conflict of interest. I've share my thoughts on this a while back (http://vuongnguyen.com/personal-business-cloud-security.html).
Now, if you haven't had a chance to use nCrypted Cloud, give us a try: http://ncryptedcloud.com. We do client-side encryption and work on top of Dropbox and shortly other cloud providers. We're free for regular consumer. The enterprise clients we have a usually more interested in the integration, management and control mechanisms we have in place.
PS: Please feel free to contact me if I could be of any help. My email is in profile.
Also, notice the phrasing: "With separate Dropboxes for personal and work, administrators can have the control necessary to secure company data, and you can still have your most important stuff at your fingertips." That sounds suspiciously like a sentence that says nothing at all, considering it's already easy to run two dropboxes, and all the problems I listed concern fully administered business accounts.
Remote wipe will be nice though.
