If you're going through the trouble of setting up realtime I wonder if you
would get any benefit from the config wizard approach.  Having said that,
see below.

Although the ast_sorcery_* API doesn't expose it, an object can be mapped
to multiple wizards, right?  What if the compound object was stored in, and
retrieved from,  one of the concrete wizards but the objects it creates are
created in a memory wizard that's added to the object_type's wizards
container.

Unfortunately, this doesn't address the real time aspect of realtime.  If
you make a change to the backing compound object data store it's not
automatically propagated to the created objects.   This brings be back to
my question above...  If you're using realtime are you likely to even need
the wizard approach.

I'm still thinking.
