From February 24, 2013:

ownCloud is a free software suite, written in PHP, that provides file storage, synchronization, and sharing. It provides the same basic features of Dropbox or Box.net. It also provides a whole lot more.

via Meet ownCloud 5, The Open Source Dropbox | TechCrunch.

Installed on your own computer, you could have most of the benefits of Dropbox, and then some, without storage limits. Anything on your computer, available anywhere and from any device? Very interesting.

From the perspective of this connected device fantasist, if ownCloud could be extended to watch for files that have been saved, modified, or otherwise accessed anywhere in your ecosystem of connected devices and services and build a chronological and otherwise sortable and searchable representation of them, then we could have the foundation for an ecosystem-wide "File Stream", which, by analogy to iOS' Photo Stream, could be stream of every file you've touched recently (subject to options and preferences, of course), automatically making them more easily available.

This would definitely be one aspect of how my fantasy Personal Digital Infrastructure (PDI) or ecosystem of devices would serve me elegantly. It would make it that much easier to work or play seamlessly as I switch devices throughout my daily life. Hmmmm.
