Hmm, the link to the demo redirects to an unrelated techcrunch article. Heres the demo: http://www.appcubator.com/resources/editor/

This is fantastic. I like seeing YC's investing in a lot of tools that will make prototyping and building easier, lowering barriers to creation for all types of makers.

Lots of potential scalability here, too. Rock on.

Nice name. I hope to become a master appcubator!

We would appreciate any feedback! - Ilter

Looks quite good, actually.
