Yes.

This will list all the meta_types that the current user has
permissions to manage:

<dtml-in "filtered_meta_types(AUTHENTICATED_USER)" mapping>
<dtml-var name>
</dtml-in>

And this will list them all:

<dtml-in all_meta_types mapping>
<dtml-var name>
</dtml-in>

Both of those will do the right thing in either a folder or a ZClass
ObjectManager.
