I use bittorrent sync for a lot of stuff, including a directory of RTF notes I take. While I'm on my mac I use Notational Velocity to edit them which is my favorite notes app ever. I haven't found a good way to edit the rtf docs on my android phone, though, which is kind of crucial. If anyone has a good solution involving bittorrent sync that is compatible with notational velocity on the mac, I'd love to hear it.
