Sal Khan represents not just one curriculum, but a new way to thinking about education: teaching basic principles behind the scenes and bringing student participation/collaboration to the fore.
We created ShowMeApp.com exactly for this reason - so that any teacher can easily create these kinds of videos through the iPad and share them online.
I participated this year (Easel), and I had a great experience. I would agree with their focus on the business aspect, particularly biz dev, in which the partners are superstars.
Besides that, it's pretty awesome to work 24/7 alongside smart entrepreneurs dedicated to helping one another out - I would almost say I got more out of the fellow entrepreneurs than the DreamIt partners.
It definitely accelerated our company's development, both on product and business.

We're huge fans what Sal is doing and would love to see more teachers embrace his approach.
We're still in beta, but I'd love to hear any feedback on the site and the app.
