I'm working on a VM/ec2 image for Gitorious to ease the installation pain. I'm working from the the Ubuntu installation script that the Gitorious project provides, and I will try to get the improvements merged upstream. Things are mostly working, so I will be making the work public after a few more days of testing. Feel free to contact me if you'd like more info.
I have seen only one company use QR codes in a local newspaper. It was in the Kansas City Small Business Journal, and the company advertising does print, design, and mail campaign work.
I have used QR codes on a few flyers and posters. The majority of people who talk to me about the QR codes I use don't realize their phones can read them.
