Wow, thanks Sig! That really means a lot!

Hey David...
Question about the cold staking.
So we have 2 private keys running on 2 different computers as a joint account.
But what if one of the keys was on one computer and the other private key was a joint account key with 2 keys on 2 separate computers.
Wouldn't that make a joint account with a joint account and virtually create a system with the capabilities to hold a 'hot' cold wallet on 3 computer devices?
Couldn't that make for an endless loop of security?
As the 2nd key could keep splitting into 2 more keys?
So if an exchange like bittrex wanted to stake the coins (on average they've held around 115 million Bays for 2 years - that's a lot coin minting power they are throwing away!), they could essentially have the cold wallet on 4 to 5 different devices, passphrase protected (with timed anti-keylogger security), and hidden in images?
It would make it unhackable! They only way they could hack the system is if it's an inside job.
Heck with this in mind they could even create a money back guarantee because they know it would have to be an inside job if it happened!
