So what you want is to create objects. Classes are just an implementation detail to creating objects :). Factories create objects, whether they're from a class is immaterial. So, what you want is not a list of classes but a list of factories that can create IContainers. This is possible by using zapi.getUtilitiesFor(IFactory) and then checking each factory's getInterfaces() method whether IContainer is a part of the returned result. I would probably base an implementation of all on the UtilityVocabulary.
