Great, are the other geronimo*.xml descriptors still required (e.g.
geronimo-jetty.xml, geronimo-application.xml, etc.)?

I thought that the serialized configs contained an arbitrary graph
of objects and that was why building a viewer was a big PITA? Am I
mixing up two different things here?

Whoops, I asked the question above twice ;-).

Sort of.... the attributes can be objects and these objects can hold
references to the values stored in other attributes (e.g., you get an
arbitrarily complex object graph).

Then it sounds like it is still possible to build a viewer. From a
single Configuration object, I'm guessing it's a collection of N
GBeans. If so, it shouldn't be too difficult to walk the collection
and ask for the constructor, methods, etc.

Only the geronimo-ra.xml is required.

It does. This is a single Configuration containing N GBeans with N
attributes.

Any JSR-88 client tool can do it - if you can find one :-)
Seriously, the provider interface is there, we just need to wrap it up
in a command line utility. The priority for this was Maven and Ant tasks
to support developers but a standalone command would be welcome as well.
