There's third option which you forgot - scanning QR codes by camera,
for example when you want to send coins to mobile phone which you
physically have in your pocket. AFAIK currently there's no easy way
how to do it (you need to transfer bitcoin address from mobile phone
to your desktop client).

The patch is really small, I recommend you to read it and you'll
understand quickly :-).
