In case anyone from launchrock is reading this: I'd be much more likely to use launchrock if I could embed the relevant functionality (signups, sharing, referrals) using javascript.
You're about to reimplement every tool that somebody would want to use to set up a landing page, beginning with an editor. What if I want to use a wordpress blog as my landing page. What if I wanted to embed the launchrock lead gen tools with some announcement that is posted on another site? I think that'd be useful and you wouldn't have to build so many things.
