I started working through a GUI design for secure multi-device wallets a couple months ago: @p{brk}

But to be secure, I think we need the @p{(link}payment protocol@p{link)} first, because otherwise an attacker can simply replace the bitcoin address given to the first device and trick you into paying them.
