You got my hopes up that we'd finally be able to audit Bittorent Sync.
At least it does mean I've got some extra encrypted-on-the-wire and encrypted-at-rest data floating around - I strongly suspect BTSync's SHA256 encrypted wire protocol moving AES encrypted EncFS files means that data is secure against the NSA's ubiquitous surveillance programs - the cleartext of those files won't be showing up in XKeyscore in response to bored or curious NSA (or Boos-Hamilton) staff. (While acknowledging that if the NSA becomes interested in _me_ specifically (or probably interested enough in any of my social network) - my privacy will be easily and wantonly violated. And I'm actually _mostly_ OK with that.)
Perhaps there should be a kickstarter for an open source bittorrent sync clone?
