I wrote this in early January 2012, but never finished it. The research and thinking in this area led to a lot of the design of Yeoman and talks like "Javascript Development Workflow of 2013", "Web Application Development Workflow" and "App development stack for JS developers" (surpisingly little overlap in those talks, btw).
