Much appreciate the step by step description.
...Thank you Mr. Jones. Ingenious!
I've created paper wallets in the past for BTC, offline method.
I think I can do it!
I use Linux Mint, so will try the live cd also. Very Cool idea.
"create one transaction out of your cold storage after you have created the address"
"it will make your address secure and record it to the blockchain"
I assume that the last step to create a withdrawal transaction, is also so that the network/blockchain will know where to send my dividend shares for all my assets?
No. Dividends are sent to account owning the assets. When you transfer assets to your cold storage account dividends will go to that cold storage account.
Every account should have 1 outgoing tx in order to be safe(r) against some attack (tech stuff). Or, at least have 1 incoming tx with public key included in tx (more tech stuff).
My advice if you want to make it simple:
1. Transfer small amount of NXT to your newly created vapor cold storage account. Make sure you write down passphrase generated by vapor.
2. Try it out! Try to send from offline account by copying tx and broadcasting transaction on your online computer. By doing this you will solve both security and know it's working.
3. When done testing send all your assets to cold storage.
