The video published on the project's main page mentions Dropbox as one of the examples that could be recreated as a distributed system with this project, but I couldn't find any info on the more interesting question: how?

Which of its facilities would be useful for that? Who would store the data? Would it be a separate system which just happens to use ethereum for user authentication, or would it actually has anything to do with data storage? How would the insanse amount of data stored distributedly in a way that it doesn't choke the individual nodes, but would be readily available any time?

Dropbox really stands out of the other example applications and without at least some basic techincal description it sounds like just a marketing stunt... so can we have some more info?
