Have you thought of throwing up an email-collection landing page, and putting a few bucks into Adwords to gauge demand? If there's nothing else in this space, you may be on to something, but you'll have to do some legwork to generate interest.

This looks like something that could work well as SaaS, I'm not sure you'd get enough traffic for ads to work out for you.

BTW, the graphing library is beautiful, but you might want to outsource some logo and design work.

Good luck!

Thanks for the input, solid points. Will rethink design. Good idea on email. Yes building interest is the name of the game. Considering blogging, SEO, SEM for long term organic growth but I like the Adwords idea for short term.
