I think this is a really nice feature for nonprofits (one of which I'm starting - I was going to go with a standard crowdtilt page, but now I'm thinking it might be worthwhile rolling out a crowdhoster one...)
It'll be interesting to see how this plays out with ShopLocket making a solid play in the "after Kickstarter but before shipping" space.
We've been using and loving Celery (http://trycelery.com) who is in this space too. Not sure about ShopLocket but we integrated Celery into shopify easily and they do discount codes and analytics via their backend dashboard as well
