We sat down with Todd Fast to talk about zembly , the world's first development environment for building cloud based social applications. Zembly is a new collaboration platform for writing small, and lightweight web apps. It's aimed at small, long-tail developers, and attempts to lower the barrier of entry to writing applications for social platforms such as Facebook , Meebo , OpenSocial and the iPhone by sharing services and widgets. Zembly is funded by Sun Microsystems and is currently in private beta.
