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
