Invite Google to take a stake in your project. It could be the first showcase featuring Google Glass. Every customer who wants them, is loaned a pair of Google Glasses during their visit. Just imagine the kinds of specialty apps you could offer! Imagine the kind of positive publicity this could generate for both companies! Invest in a Google Glass developer's kit & whip up a prototype to show Google when you pitch this to them. I hope you live on, as the first AR bookstore!
