I really like these ideas, and I'd love to see one of them go. I did notice the demo url was 127.0.0.1 though... I know, it's just a demo..

That said, one question.. Do you guys work 100% in your own IDE? And hosted (not localhost)? I think that's a must if you want other shops to use it.

Also I think a zero-barrier demo on your site would be huge. I ought to be able to click a link, land in an editor, and write some running code, a-la the mongodb shell on their site.
