I did the same thing today, I was glad I got the same public key, I am guessing that means I set the second computer up correctly. I am guessing with no blockchain, there is no way for it to sync messages?
Both computers will receive messages. And messages are not stored in a blockchain. We are working on a solution that would allow both machines to get old messages as well.
Are current IPs of individual users stored in a blockchain, or does it use distributed hash tables or something else for this?
In either case I expect you're looking at a solution rather like BitTorrent Sync with all data encrypted to yourself. Can this be generalized so Keyhotee provides a synchronized general storage directory rather than just syncing emails, messages, and contacts? Also, could Keyhotee allow users to grant friends a storage quota?
Just brainstorming, so this may be overcomplicated, but if you apply a RAID-like system across your network of friends, it could handle automatic message recovery in case of system failure, as well as syncing between machines without having to leave both powered on simultaneously.
In this case you could also rank friends by how much storage space they're worth, allowing some interesting and potentially dramatic social price discovery...
