I bought 'qrko.de' for nearly the same purpose: URL shortening with bit.ly style analytics but with built in QR support (and maybe user-agent tracking. It would be interesting to see the device market share for code scanning)
I'll probably still build it; it bums me out the the goo.gl shortener is semi-closed.
Kudos to Google on this. They've really been pushing QR and that's exactly the kind of support needed for it to reach critical mass. Reading QR codes is one of the few ways my Droid can school the iPhone...
As far as I'm aware, there are a ludicrous amount of patents surrounding the use of QR-type codes that link to URLs. I remember NeoMedia in particular being singled out by the EFF for having a stupidly sample patent on the linking.
I'm now curious to see who wants to take on Google's strength when it comes to this game ;)
Something else to checkout with Google and QR Codes is Google's [QR Code Chart API](http://code.google.com/apis/chart/image_charts.html). It is the most dead simple way to create QR Codes that I've found.
There are just so many uses for this... Everyone from print+digital content providers (local magazines, papers, etc) to ma and pa IT shops can use such a service...
I know that it's nothing new, but the fact the Google is putting it out there pretty much ensures its wide-spread adoption (more so, anyways)...
Practically every Japanese cell phone has a built-in utility for reading bar codes. Any printed advertising material that contains an URL will also have a QR code.
Dammit!
edit: I am even in mid-process of acquiring a .et domain so I could've had http://mark.et/whatever. Gah!
