“JavaScriptCore is a part of the open source WebKit project. Instead of using the private library that comes with iOS, you theoretically could compile your own version of this library and bundle it together with your App. Which is exactly what I did.”

This news has me very excited indeed. If Apple does indeed allow apps which bundle the source for an otherwise private library, this makes it much more likely that I’ll be able to create a customized epub layout engine based on WebCore. Which in turn makes support for epub v3 in Kobo ever more likely, albeit at a dramatically increased application size (WebCore+JavaScriptCore is somewhat large).
