Just like the dev fabric however enable this as a production feature within IIS 7+.

This means develoeprs will be able to create solutions within the Azure project templates and framework but run on a local machine. This will allow companies that want to start small and within their own boundaries/infrastrucure to easily migrate from onpremise to the Azure cloud with ease as no project structure changes would be required (or very little)

Plus, this approach would also allow for the switching of on premise to cloud and vice versa in case of outages. Build in this "swap" function within IIS or someother MS tool.
