Sounds great idea. There should be online store with almost all kinds of digital goods and services. They can use digital payment such as bitcoin and it will work because of the fact that its DIGITAL. :-)
This can open whole new doors for the digital marketing and there is big crowd which loves bitcoin and want to buy stuff with it. I have seen so many people asking about the websites or off line stores which accepts bitcoin as mode of the payment. I hope there will be lot of us going to open a new ways of earning by setting up such stores around the globe. It will beneficial for us as well as people who wants to spend in terms of bitcoin currency. Nice thought BTW.
