Excellent innovation. This is like waving a red flag in the face of the MPAA, RIAA, and all the other entrenched monopolies that are seeking to extend their outdated business models by using old-school Mafioso tactics. I would be very surprised if Boxopus, Dropbox (or both) wasn't pressurized to discontinue this service in some way. API changes by Dropbox (or TOS violation based suspension), Lawsuit for BoxOpus, etc to follow...
