It would be nice to have a custom linux distro that could be installed on a usb key for using such things as freenet, bitcoin and tor.Could you transfer bitcoins by mail on the stick by using private key encryption to ensure the usb key is trusted?Would this be safer than posting money orders,cheques or cash for payment?Could you set your payment to expire after a certain time period so that if the usb key was lost or unclaimed you could have your bitcoins returned ?It seems that since the network knows the history of each bitcoin it would know if they have been redeemed or not.
Does any of this make any sense
