I think that p2p file sync has big potential. For those that are interested, I've done an analysis of p2p file sharing generally (in context of recent announcements and as versus cloud-based solutions), and of BT Sync specifically after Kos was kind enough to send me an invite for the pre-alpha. p2p v cloud analysis here: http://www.agentofkaos.net/2013/02/p2p-file-sharing-dropbox-killer.html BT Sync specific review here: http://www.agentofkaos.net/2013/02/a-closer-look-at-bittorrents-syncapp.html Comments here or there welcome! AoK (nb: after reviewing the forum, one comment about security particularly resonated with me - I liked the idea of using public/private encryption between each node in the mesh as an alternative to AES256 one-way encryption. Seems like a really good way to lock security down hard and avoid an unintentional proliferation of the "secret".)
