I can't show you the code because it is proprietary, but maybe you'll find this useful. At my place of work we are in the process of moving over a hundred apps of differing levels of complexity into a single app suite. Each app is simply a pluggable module we add to the suite, with user permissions, and it just works. So far we've moved about 20 apps (and created some new ones) and it is working great. My only advice would be to make sure any shared resources between "apps" have full testing implemented from the beginning.
