Ooops. I forgot to address this.

I now understand what you mean by two worlds. I'll think about what can 
be done in the library to accommodate for such a case. For now it won't 
be possible to separate the logic between two sets of objects.

The library provides something that's vaguely similar to this: domains. 
The domain is a set of mixins and messages that don't mix. You could add 
the same class and same messages to many domains and thus you'll be able 
to have your two worlds, but you won't be able to have N worlds, because 
you'll have to have the code

BOOST_DEFINE_MIXIN_IN_DOMAIN(domain_a, some_mixin, features & a_allocator);
BOOST_DEFINE_MIXIN_IN_DOMAIN(domain_b, some_mixin, features & b_allocator);
...

But if the number of worlds is determined at runtime, this won't help 
you, plus managing will be a real nightmare with all the same internally 
generated names.

Still I think I'll be able to do something in this regard. I'll think 
about it.
