I'm not a user of it yet, but by chance I noticed your activity mixed into the git-ssb-web feed the other day, including commits on keysafe, which I had never heard of before.

Then today, looking over the project's github repos, I noticed an attempt at a Shamir's Secret Sharing backup system. It seems to work by just sending the shares to your choice of friends. As I understand it, unlike email, it not possible for them to delete the message.

Although compared to keysafe's independent servers, it seems much more possible for two people you know to both have been compromised (or just to collude, but presumably they'd have a good reason for doing so).
