The key thing to note, here, is that you'll actually have 4 apps (3 individual apps and one combined app). This is ignoring the staging/live distinction because staging and live are just copies of each other in different directories.

Create each of the individual apps and get them responding on their individual domains. Then create a new app that imports the application variables from the individual apps and combines them using the DispatcherMiddleware like the example under the heading "Combining Applications" on the doc page you link to.
