So this will run on RasPi?
It seems like the next step is for someone to attach a NAS to a RasPi and make a "syncbox" -- a NAS which auto-syncs to the other NASes you've configured across the internet.
For end users, they would get 2 and share a secret between them, then install one at 2 separate offices (or home and office), and any files dumped onto one NAS are replicated to the other. Basically Dropbox without file limits.
