This is also nice demo for JS canvas based QR code generator. http://www.cipherbrain.be/qrcode/
It would be nice to have kind of utility jquery plugin part of the shipped one that could return a QR code for document or database or server Url. The same with shortener that then could apply for each server domain. I still think this are useful features being a part of modern web development as the CouchDB it self.
