Do you like the smell of books?

Tired of just reading comics on your computer screen? Now you can get the full comic reading experience with the new Smell of Books product from DuroSport Electronics.

This aerosol can is causing quite a stir. See:

I sense a business opportunity here. Should I franchise the Smell of Books product? Or is Smell of Comic Books a different enough product that I wouldn't be infringing on any of their patents?
