So, basically, Revilo Sync (formerly Bittorrent Sync)?

Resilio Sync you mean? I use that at work already, and I considered this solution yeah. My main problem with it is that they only provide pre-compiled binaries, and there all users have the same access to the data. I'd prefer a solution with builtin encryption support, so that even if my data is spread amongst 10 servers, I'm still the only one able to access it (given that I don't loose the key of course).
I like the idea of using bittorrent underneath though, as it's pretty efficient network-wise, and fault-tolerant as well. I considered syncthing as well, but many users reported loosing data because of it, which makes it a pretty bad backup tool!

I started cooking something on my own for this purpose (see synk). For now it's just a multihost rsync, but I plan on having it support directory recursion, and non-POSIX systems as well. I would love to implement it over bittorrent, but couldn't find a simple library to use the protocol in C, so for now I keep calling ssh + rsync (and it works rather well for now).
With this solution, encryption needs to be done outside the tool, for example:


That's no rocket science as you can see, but still require external tools.

Now that's a good idea. I'd had fist bump as well, to keep entertaining the suspense when the arm moves ;)
To go slap only, a servomotor and a rubber band would be enough I guess. Then to slap, you perform a full rotation with the rubber band.

Now you need to create and RFC for that protocol
