I would to like suggest that an option to restrict sync to a list of peers be implemented. As I understand the current known hosts option doesn't work that way. In my case I would like to restrict sync to machines in my local network (192.168.x.x). Imagining a worst case scenario where the secret code is compromised, the attacker wouldn't be able to access the info unless his machine was part of said list (or in my case part of my local network). It would be even better if the OS' admin credentials would be required in order to view/edit the list. EDIT: Sorry just noticed there's a "Wishlist" sticky, I've completely missed it. My apologies.
