The problem I see for so many entrepreneurs is that they (we) simply don`t have the money to do everything they`d like to accomplish. They often are thrown into their own DYI resources to build a Web site, handle marketing, build this or that, and generally take care of everything.
There are templates out there, turnkey stores, and so forth, but with a little bit of extra knowledge---not a huge amount---people can build a Web page or small site without using a template. However, it`s going to be pretty basic.
So in this situation, the entrepreneur---usually bootstrapping---can only do the basics, which means that any sort of demo for their product(s) is part of a Web page.
What I`m thinking, relative to your product, is that if it`s that simple and affordable, people could simply put a button or link onto a page along the lines of "View Demo" and then have the sales presentation run separately from the page. That way, when they`re done viewing the application, they close out and end up right back where they started.
For example, right now, in order to show people the details of our signal flags, we have to have separate pages and images. The content links to this and that page, opens blank windows, returns the person to pages, and generally follows the circuitous route of many typical Web pages.
What would be nice would be to have a link on our "about" page to a presentation that follows the development of our flags from start to finish. The user would click the button/link and your application would begin. It would have the "next" and "previous" options like building a slideshow. People could see the details of the flags in a moving, dynamic way, and when they`re done, close out and be right back where they started.
If it`s really as easy and user-friendly as you say, then it seems to me this would be an excellent low-end solution until people could afford a Flash! animation, embedded video, or some of the other, more sophisticated tools. See?
Actually, thinking about it, you might even expand and offer editorial services after you`ve launched the product. In other words, developing the application is sort of a one-time thing, and after you`re launched, you either develop something else or you handle ongoing tech support.
But you could add a revenue stream by offering to take user content, emailed to you, and then you or your employees would turn it into a presentation. Then invoice the customer, and after they`ve paid, send them the link. Maybe not something you want to do, I`m only suggesting a sort of parallel-track product line.
