That depends on what you mean by "support". module() in luabind is
really just an alias for namespace_, which can be used only at
top-level, but you are right that we could probably support something
similar.

One thing; the converter-registries aren't really bound to modules though 
are they?
They are really just bound to the shared library. So if you have multiple 
modules
in the same shared library you would automatically share registries as well.
