I agree, make the demo one of your calls to action on the home page.

Generally speaking, without a demo I wouldn't spend any more time investigating this type of app.

I have some design comments.

How about mouseover states for everything that does something, buttons, links, the three top of page links etc

Couldn't understand the -0+ rating system quickly enough. Actually going back to it I can't understand it at all and don't want to give it any more time figuring it out.

All type rendered in Museo via typekit is very ragged for me. I think most of it would look better via cufon.

Overall very impressed, both with the concept which I think has a lot of value and the design.
