Linking from real life objects via QR codes

I’m using paper based material in my GTD system too, linking to that is really hard.

Hook could generate a QR code to any link, so I can print and attach it to paper based folders for example.

Later Hook could scan QR codes by the Mac’s camera and bring up OmniFocus projects, Pages files, whatever we need.

Maybe it sounds dumb and not something I consider high priority, but I wanted to leave the idea here for consideration.
