Hello.
I thought of an interesting idea.  If a person were to encrypt a wallet and print the encrypted data as a barcode, this could work like a money order, but more secure.  The encrypted wallet could be mailed and the encryption key could be given over the phone, through an email, through the website in which you have placed your order, or simply be memorized and given in person.  This could also allow a person to carry paper Bitcoin money with little chance of the money being stolen even if robbed.  This would also prevent someone with a camera from being able to steal you wallet in barcode form.  This could even make Bitcoin easy to use for people that aren't very computer savvy.  A person could just go to his/her bank and have Bitcoin money printed.
