So basically this is good if you need the flexibility of Cloud based apps like Dropbox or Box with the convenience of data ownership and storage.

It is interesting to see that folks can "replace" dropbox with ftp/ssh/rsync/webdav etc. But the strength of dropbox or similar solution (self-hosted or otherwise) is the consumability model (music transcoded and streamed, Photos resized and presented as slideshows, controlled share support). With more and more access to the data coming from mobile clients, the differentiation of these services from those "traditional access services" are their support for new mobile clients/OSes.
