I've mentioned previously here that on my "somebody should create this, and I might eventually" list is an open source, P2P, optionally server-backed, encrypted Dropbox replacement. Upon further thinking about the concept in light of the recent NSA stuff, I contemplated the possibility of building a social network on top of such a system that allowed for sharing files with friends. It looks like this project is basically an implementation of this idea. Nice one.
