This is also a very good argument for smartcards - transferring a
private key between devices is error-prone and potentially catastrophic.
Yes, it can be done securely but for non-experts (and even experts!)
having a physical "key" is much more intuitive. How often have we heard
of people accidentally distributing their private key instead of their
public one? Few of them will have a 128-bit secure passphrase like RJH. :-)
