Keep your eye out for upcoming updates to Dropbox for Business. Looks like upcoming features will cover most of your points: https://www.dropbox.com/business/two-dropboxes
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.
