This is interesting. Another use for such a secure machine would be to enter text, eg highly controversial blog entries or erotic stories. Then any common computer or phone with a camera can be used to transfer the text using 2D barcodes.
This would be a bit slow: say a barcode. If we assume a single barcode can hold 1500 characters (text twice as long as your comment), a blog entry may need 4-5 barcodes. Not undoable.
Such a machine would not have a camera, WiFi, BT, or any input or output mechanism of any kind.
