Yes, Guice can be used in the model that an Injector represents the container in which objects of an app are configured and instantiated. That's a good way to go for a large set of cases.
An extension thereof is to use Guice to handle lifecycles as well. To handle an initialization-based lifecycle, it's convenient to use the Service<http://code.google.com/p/guava-libraries/source/browse/trunk/src/com/google/common/base/Service.java?r=74>class, and especially the AbstractService<http://www.google.com/codesearch/p?hl=en#UKMs0lhE9bg/trunk/src/com/google/common/util/concurrent/AbstractService.java&q=AbstractService%20package:http://guava-libraries%5C.googlecode%5C.com&sa=N&cd=1&ct=rc>template. These classes are included in the Google Guava <http://code.google.com/p/guava-libraries/>libraries. A basic pattern to follow is to create a Set<Service> using a multibinder, and then inject that into your main class or an application entry point. Something as simple as that typically does the trick. This is preferred over using initialization in modules because of the intrinsic multithreading you can achieve with AbstractService subclasses.
