I don't really see an advantage to hiding the fact that the software is free. I think the best way to go to market with media signage is to simply set them up with there own free account that includes their first initial phase of content and go from there. Like for example: Mr. Customer, I'll set you up with your own account that includes the software and your initial content for x$. Business owners do not have the time to learn how to use this software, create content and manage it to keep it fresh. The digital signage entrepreneur has to generate the income from the content creation and content management side of the business. Just my 2 cents.
